Because of this, it needs + * a second block of memory in order to + * store control information. You have to + * predefine a fixed number of memory + * blocks that can be used.

d1_memsize

extern unsigned int d1_memsize(void *ptr)

Returns the size of the given memory block

Parameters

ptrpointer to a memory block in Heap

Returns

intsize of the memory block.
+ +

d1_allocmem

extern void * d1_allocmem(unsigned int size)

Allocates memory on the CPU heap

Parameters

sizeSize of the memory to be allocated

Returns

void *Pointer to the start address of the allocated memory block 0 if not successful
+ +

d1_freemem

extern void d1_freemem(void *ptr)

Free the specified memory area on the CPU heap

Parameters

ptrPointer to the memory area to be freed

Returns

None

+ +

d1_allocvidmem

extern void * d1_allocvidmem(d1_device *handle,
int memtype,
unsigned int size)

Allocate video memory

For systems without a unified memory architecture all memory that will be accessed directly by hardware has to be video memory.  On a UMA platform d1_allocvidmem will most likely behave just like a simple malloc.

Note that not every platform will make use of the ‘memtype’ it is used as a hint in order to get the memory best suited for the specified purpose.

All memory allocated using this function must be released by d1_freevidmem

Parameters

handledevice handle (see: d1_opendevice)
memtypetype of memory (see list below)
sizenumber of bytes

Memtypes

d1_mem_displayused if the memory is going to be displayed (framebuffer)
d1_mem_textureused for textures (accessed by dave but not by the displaycontroller)
d1_mem_dlistused for display lists (read only for hardware)

Returns

pointer to memorychunk or NULL.

the pointer returned by allocvidmem points directly to video memory and can not be accessed by the CPU (unless the memory architecture is unified - see d1_queryarchitecture).  Transfer functions like d1_copytovidmem and d1_copyfromvidmem can access video memory directly.

+ +

d1_freevidmem

extern void d1_freevidmem(d1_device *handle,
int memtype,
void *ptr)

Release video memory

The memtype should be identical to what has been specified when allocating the block.

Parameters

handledevice handle (see: d1_opendevice)
memtypememory pool id (see: d1_allocvidmem)
ptraddress returned by d1_allocvidmem

Returns

None

+ +

d1_queryvidmem

extern int d1_queryvidmem(d1_device *handle,
int memtype,
int query)

Get current memory status

Not every platform will treat all memory pools as distinct heaps, so the return values might be the same for different memtype’s.

Parameters

handledevice handle (see: d1_opendevice)
memtypememory pool id (see: d1_allocvidmem)
querytype of requested information (see below)

Query types

d1_mq_installedsize of installed memory
d1_mq_availablelargest available free chunk
d1_mq_freetotal amount of free memory
d1_mq_allocatedtotal amount of allocated memory

returns

number of bytes

+ +

d1_mapvidmem

extern void * d1_mapvidmem(d1_device *handle,
void *ptr,
int flags)

Map video memory for direct CPU access

In order to access video memory directly with the CPU it has to be mapped into system memory (unless the host has a unified memory architecture).  This function always maps an entire block (as allocated by d1_allocvidmem) and therfore does not need a ‘size’ argument.

Mappings must be released before the memory is freed by d1_freevidmem.

Parameters

handledevice handle (see: d1_opendevice)
ptrvideo memory address returned by d1_allocvidmem
flagsmemory mapping flags (see below)

Memory mapping flags

d1_mf_readmapped memory will be read only
d1_mf_writemapped memory will be written only
d1_mf_readwritefull access to mapped memory
d1_mf_directtry mapping to the same address (make videomemory visible to current process using its original address)

Returns

CPU accessible pointer to the same memory region

See also

d1_unmapvidmem

+ +

d1_unmapvidmem

extern int d1_unmapvidmem(d1_device *handle,
void *ptr)

Release memory mapping

Memory mapped using d1_mapvidmem should be unmapped before it is released.

Parameters

handledevice handle (see: d1_opendevice)
ptrmapped video memory address returned by d1_mapvidmem

Returns

boolean success.

+ +

d1_maptovidmem

extern void * d1_maptovidmem(d1_device *handle,
void *ptr)

Map CPU accessible address of a video memory block back to video memory address

In systems, which have CPU and hardware address spaces statically mapped to each other (see: d1_queryarchitecture), this function can be used to convert an address inside the CPU address space and pointing to a block of video memory back to a video memory address.

Parameters

handledevice handle (see: d1_opendevice)
ptrCPU accessible address pointing to a video memory block originally allocated using d1_allocvidmem

Returns

hardware accessible pointer to the same memory region or NULL if mapping not possible

See also

d1_mapfromvidmem

+ +

d1_mapfromvidmem

extern void * d1_mapfromvidmem(d1_device *handle,
void *ptr)

Map already allocated video memory address to an address for direct CPU access

In systems, which have CPU and hardware address spaces statically mapped to each other (see: d1_queryarchitecture), this function can be used to convert a video memory address to an address in the CPU address space.

Parameters

handledevice handle (see: d1_opendevice)
ptrvideo memory address returned by d1_allocvidmem

Returns

CPU accessible pointer to the same memory region or NULL if mapping not possible

d1_queryarchitecture

extern int d1_queryarchitecture(d1_device *handle)

Return hints about systems memory architecture

The application can often avoid memory transfers if a unified memory architecture is available on the host system.  This function can be used to query the host memory architecture.

Parameters

handledevice handle (see: d1_opendevice)

Returns

a bitfield with the following bits set if applicable :

d1_ma_unifiedCPU can directly access pointers returned by d1_allocvidmem.  Transfer and mapping functions will work but are unnecessary.
d1_ma_separatedVideo memory is separated from CPU memory and can be accessed by copy or mapping functions only.
d1_ma_uncachedCPU access to mapped video memory is not cached.
d1_ma_fullumaStatic arrays and malloced memory can be accessed by the hardware.
d1_ma_mappedAllocated video memory is statically mapped into CPU memory.  Use d1_mapfromvidmem and d1_maptovidmem to convert addresses.
d1_ma_fullmappedThe whole CPU memory (malloced memory as well as static arrays) is statically mapped to the address space of the hardware.  Use d1_mapfromvidmem and d1_maptovidmem to convert addresses between CPU address space and hardware address space.

Functions

d1_setirqhandler

extern void d1_setirqhandler(d1_device *handle,
int irqtype,
d1_interrupt code,
void *data)

Register an IRQ handler

Registered callback will be called when the specified IRQ triggers.  The IRQ will be reset automatically after the callback has been executed.  Note that the callback code might run at a different privilege level than the main application.

You can pass NULL instead of a function pointer in order to remove a registered callback.

Not every interrupt is available on every platform.  Unsupported IRQs will never trigger but setting or removing a callback for them does no harm.

Parameters

handledevice handle (see: d1_opendevice)
irqtypeinterrupt ID (see below)
codecallback address (NULL to remove handler)
datauserdefined data (passed on to callback directly)

Interrupt IDs

d1_irq_breakuserbreak
d1_irq_vbivertical blank
d1_irq_dlistdisplay list finished

Callback signature

void D1_STDCALL d1_interrupt( int irqtype, void *irqdata, void *usrdata );

Note

Consider that existing ISR registrations might be disabled when setting new irq handlers.  An ISR should always call the original ISR that was registered before d1_setirqhandler was called (use d1_getirqhandler).  Otherwise, e.g. in case of the vertical blank irq (d1_irq_vbi), this will disable the display controller driver.

Heap management

Collection of heap managers, which may be used by a d1 driver implementation on a certain platform.  Eases d1 platform porting e.g. on non-UMA platforms or on platforms which don’t have a stdlib with malloc/free/msize

There are three available types of memory managers.  These managers can be used to manage blocks of memory e.g. video memory, heap memory etc.

Types of memory managers

d0_mm_dynamicWrappers for stdlib malloc, free and msize of the system.
d0_mm_fixed_rangeMemory manager which uses one block of memory for memory allocation and control structures (list of allocated memory blocks).  This manager is normally used as manager for a heap on systems that do not provide dynamic memory allocation.  This memory manager needs 42 bytes of fixed control information.  For each block of allocated memory additional 8 bytes of control information will be stored.
d0_mm_fixed_range_fixed_blkcntMemory manager which uses two blocks of memory: one for allocation and one for control structures (lists for free and used blocks).  This manager is normally used to manage memory that isn’t directly mapped to the system memory.  Because of this, it needs a second block of memory in order to store control information.  You have to predefine a fixed number of memory blocks that can be used.  Typically used on systems with separate video memory.  This memory manager needs 28 bytes of fixed control information and 16 bytes for each block of allocatable memory.
Summary

Usage

How to use the D/AVE driver memory management interface.

If you want to make use of the d0 memory management functions, your d1 platform code for d1_allocmem, d1_freemem, d1_memsize, d1_allocvidmem and d1_freevidmem should wrap the respective d0_* functions.  You then need to initialize the heap managers somewhere in your application before you do any d1 or d2 driver calls.  The simplest way is to call d0_initdefaultheapmanager.  This function registers a wrapper for the stdlib malloc, free and msize functions.  These functions will be used as managers for the video and heap memory.  In order to register different managers for the heap and video memory, you have to use the function d0_initheapmanager.  This function allows to choose different memory managers for video and heap management.

Display list handling

Support for Dave 2D to handle lists of display lists.

Dave 2D has a built in reader for display lists (Dlists).  Dlists contain commands for Dave 2D.

If the start address of a Dlist is written to the D2_DLISTSTART register then Dave 2D starts to read the commands of this list up to its end.  When the last command has been finished Dave 2D can raise an interrupt.

Summary

Default execution of single display listThe default method to execute a display list is to set the start addrress of a single Dlist.

+ +

Default execution of single display list

The default method to execute a display list is to set the start addrress of a single Dlist.

The d2 driver uses the function d1_setregister

d1_setregister(dev, D1_DAVE2D, D2_DLISTSTART, dlistaddress)

to write the Dlist start address to the Dave 2D register.

+ +

Execution of lists of display lists

The D1 low level interface can offer a special handling for lists of Dlists.  d1_setregister can be called with a pointer to a list of Dlist start addresses.

d1_setregister(dev, D1_DAVE2D, D2_DLISTSTART, &dlistlist)

In this case dlistlist is a pointer to a list of Dlist start addresses.  The D1 driver iterates this list and writes the Dlist start addresses to Dave 2D one after the other.  The value 0 is used to mark the end of the list.

A special D1 device D1_DLISTINDIRECT is used to switch the behaviour of d1_setregister between single and list mode.  The support of this behaviour can be checked by d1_devicesupported.

With

d1_devicesupported(dev, D1_DLISTINDIRECT)

the application (d2 driver) can check whether the handling of lists of display list start addresses is supported by the D1 low level interface.

With

d1_setregister(dev, D1_DLISTINDIRECT, 0, value)

the handling of lists of Dlists is activated (value can be any value > 0).

With

d1_setregister(dev, D1_DLISTINDIRECT, 0, 0)

the handling of lists of Dlists is switched off.

+ +

D1 internal handling of display lists

The handling of display lists can be done in the function d1_setregister and in the interrupt service routine.

The D1 driver must store the pointer to the Dlist list in its device structure d1_device.

typedef struct _d1_device {
+    int            dlist_indirect;      /* flag to enable dlist_indirect */
+    volatile long *dlist_start;         /* dlist start addresses, end is marked with 0 */
+} d1_device;

The function d1_setregister (dev, D1_DAVE2D, D2_DLISTSTART, &dlistlist) must store the value dlistlist in d1_device.  It also starts Dave 2D by writing the first entry of the list to the Dave 2D register.

void d1_setregister( d1_device *handle, int deviceid, int index, long value )
+{
+  switch (deviceid) {
+    case D1_DAVE2D:
+      if (index == D2_DLISTSTART && handle->dlist_indirect) {
+        int *dlistp = (int*)value;
+        handle->dlist_start = (long*)(dlistp + 1);
+        WRITE_REG( DAVE2D_0_BASE, index, *dlistp );
+      } else {
+        WRITE_REG( DAVE2D_0_BASE, index, value );
+      }
+      break;
+    case D1_DLISTINDIRECT:
+      handle->dlist_indirect = value;
+      break;

When the execution of the first dlist has finished Dave 2D raises an interrupt.  In the interrupt service routine the remaining entries of the Dlist list can be handled.

void d1_generic_isr(void *context, int id) {
+  int intReg;
+  d1_device *dev = (d1_device*) context;
+
+  switch (id) {
+    case DAVE2D_0_IRQ:
+      intReg = READ_REG(DAVE2D_0_BASE, DAVE_STAT);
+      if (intReg & 0x30) {
+        // any DAVE interrupt?
+        // clear/enable all DAVE interrupts
+        WRITE_REG(DAVE2D_0_BASE, DAVE_IRQ_CTRL, 0xe);
+
+        if (intReg & 0x20) {
+          // display list interrupt?
+
+          if ( dev->dlist_indirect && *(dev->dlist_start) != 0) {
+            long dlist_addr;
+            dlist_addr = *(dev->dlist_start);
+            /* get next dlist start address */
+            dev->dlist_start++;
+            /* starting Dave */
+            WRITE_REG( DAVE2D_0_BASE, D2_DLISTSTART, dlist_addr );
+          } else {
+            // call callback functions

D1 Driver Overview

The low-level driver provides a hardware and OS independent API to let D/AVE 2D applications run on any given platform.  This abstraction is needed by:

  • the generic D/AVE 2D level 2 driver
  • the TES D/AVE 2D EGL and OpenGL-ES subset implementations
  • the TES provided standard demos for D/AVE 2D
  • further D/AVE 2D application code

It is important to notice, that only the first point is mandatory: It is possible to implement a subset of the D/AVE 2D interface and implement all functions, which are not needed by the level 2 driver itself as stubs.

The functions required by the level 2 driver are

For a complete list of D1 types and functions see D1 API.

Memory Handling

The D/AVE 2D driver differs between normal CPU memory handled via d1_allocmem, d1_freemem and d1_memsize and ‘video memory’, handled via the ‘d1_*vidmem’ functions.  The difference between these types of memory is that CPU memory only needs to be accessible by the CPU alone and video memory needs to be accessible by both the GPU (HW) and the CPU.  Only video memory of type ‘d1_mem_dlist’ (see d1_allocvidmem) is allocated directly by the D/AVE 2D driver.

Video memory is handled differently by the D2 driver based on the return value of d1_queryarchitecture.  In general, there are three different types of memory architectures:

Unified memory systems (d1_ma_unified)

In unified memory systems, the CPU can directly access allocated video memory at the same address as D/AVE does.  Display lists are directly allocated and assembled in the video memory.  Before a display list is executed by D/AVE, the list of display list blocks is walked along and every block is flushed out of the CPU cache.

Static mapped systems (d1_ma_mapped)

Like in unified memory systems, the CPU can directly access allocated video memory.  The only difference is that the effective address is different on D/AVE side compared to CPU side.  The level 1 driver offers special mapping functions for this reason.  The display lists are handled just like on the unified memory systems.  The only difference is that the mapping functions are used to convert the addresses.

Separated memory systems (d1_ma_separated)

On systems with separated memory, the CPU can not directly access the video memory.  The level 1 driver offers special copy and dynamic mapping functions to access it.  The display list blocks are allocated and assembled in the local memory on these kinds of systems.  Before a display list block is executed by D/AVE, the whole list is walked along and every block is copied to an equally sized block in the video memory using the level 1 functions.

A special ‘low localmem’ mode is available for separated memory systems that only offer very little local memory.  On such systems it is not possible to build up the complete display list in the CPU memory.  In ‘low localmem’ mode the D/AVE driver only uses two local display list blocks.  Every time a block is completely filled, it is copied to a block in video memory asynchronously, while the second block can be immediately used by the driver again.  The final display list blocks in the video memory have a size which is a multiple of the local display list block size, so that multiple local blocks are concatenated to a single block in video memory.  Assuming that dynamic memory allocation should be avoided on such systems as much as possible, the maximum number of display list blocks in video memory is also constrained here (the driver must hold a table with the addresses of all these video memory blocks).  The ‘low localmem mode’ can be enabled and configured using the ‘d2_lowlocalmemmode’ function after a call to ‘d2_opendevice’ and before calling ‘d2_inithw’.

Device IDs

Hardware components

The lowlevel hardware control is mainly based on direct hardware register access.  Each component has its own register field.  Registers are not accessed directly by an address, but rather by a device ID and an index (see d1_setregister or d1_getregister).

The driver will map the abstract register index to a platform dependant physical register address.  Not every platform exposes the same DAVE components (availability can be checked using d1_devicesupported, register access to unavailable hardware units is ignored).

+ * + * For a fairly comprehensive set of languages see the + * README + * file that came with this source. At a minimum, the lexer should work on a + * number of languages including C and friends, Java, Python, Bash, SQL, HTML, + * XML, CSS, Javascript, and Makefiles. It works passably on Ruby, PHP and Awk + * and a subset of Perl, but, because of commenting conventions, doesn't work on + * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class. + *

+ * Usage:

    + *
  1. include this source file in an html page via + * {@code } + *
  2. define style rules. See the example page for examples. + *
  3. mark the {@code 
    } and {@code } tags in your source with
+ *    {@code class=prettyprint.}
+ *    You can also use the (html deprecated) {@code } tag, but the pretty
+ *    printer needs to do more substantial DOM manipulations to support that, so
+ *    some css styles may not be preserved.
+ * </ol>
+ * That's it.  I wanted to keep the API as simple as possible, so there's no
+ * need to specify which language the code is in, but if you wish, you can add
+ * another class to the {@code <pre>} or {@code <code>} element to specify the
+ * language, as in {@code <pre class="prettyprint lang-java">}.  Any class that
+ * starts with "lang-" followed by a file extension, specifies the file type.
+ * See the "lang-*.js" files in this directory for code that implements
+ * per-language file handlers.

+    * be called with '<script>' which would not match the same rule since
+    * group 1 must not be empty, so it would be instead styled as PR_TAG by
+    * the generic tag rule.  The handler registered for the 'js' extension would
+    * then be called with 'foo()', and finally, the current decorator would
+    * be called with '<\/script>' which would not match the original rule and
+    * so the generic tag rule would identify it as a tag.
+    *
+    * Pattern must only match prefixes, and if it matches a prefix, then that
+    * match is considered a token with the same style.

handle.&nbsp; A device handle (see: <a href="dave_driver-c.html#Device_management" class=LGroup >Device management</a>) is the root of all process dependant data and is passed as first parameter to every function.&nbsp; This construct allows the driver functions to be reentrant in case of a multiple drawing engine units.</p><p>A device handle contains information about displaylists, framebuffers,etc...&nbsp; Everything that the drawing engine will require.&nbsp; It also includes pointers to contexts.</p><p>Each device has at all times pointers to three relevant context&rsquo;s

solid and outline) can point to the same context.&nbsp; Every driver function that starts with <b>get</b> or <b>set</b> will work on the currently selected context (with the obvious exception of

+/**
+ * @fileoverview
+ * some functions for browser-side pretty printing of code contained in html.
+ * <p>
+ *
+ * For a fairly comprehensive set of languages see the
+ * <a href="http://google-code-prettify.googlecode.com/svn/trunk/README.html#langs">README</a>
+ * file that came with this source.  At a minimum, the lexer should work on a
+ * number of languages including C and friends, Java, Python, Bash, SQL, HTML,
+ * XML, CSS, Javascript, and Makefiles.  It works passably on Ruby, PHP and Awk
+ * and a subset of Perl, but, because of commenting conventions, doesn't work on
+ * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class.
+ * <p>
+ * Usage: <ol>
+ * <li> include this source file in an html page via
+ *   {@code <script type="text/javascript" src="/path/to/prettify.js"></script>}
+ * <li> define style rules.  See the example page for examples.
+ * <li> mark the {@code <pre>} and {@code <code>} tags in your source with
+ *    {@code class=prettyprint.}
+ *    You can also use the (html deprecated) {@code <xmp>} tag, but the pretty
+ *    printer needs to do more substantial DOM manipulations to support that, so
+ *    some css styles may not be preserved.
+ * </ol>
+ * That's it.  I wanted to keep the API as simple as possible, so there's no
+ * need to specify which language the code is in, but if you wish, you can add
+ * another class to the {@code <pre>} or {@code <code>} element to specify the
+ * language, as in {@code <pre class="prettyprint lang-java">}.  Any class that
+ * starts with "lang-" followed by a file extension, specifies the file type.
+ * See the "lang-*.js" files in this directory for code that implements
+ * per-language file handlers.
+ * <p>
+ * Change log:<br>
+ * cbeust, 2006/08/22
+ * <blockquote>
+ *   Java annotations (start with "@") are now captured as literals ("lit")
+ * </blockquote>

+    * '<script>foo()<\/script>', which would cause the current decorator to
+    * be called with '<script>' which would not match the same rule since
+    * group 1 must not be empty, so it would be instead styled as PR_TAG by
+    * the generic tag rule.  The handler registered for the 'js' extension would
+    * then be called with 'foo()', and finally, the current decorator would
+    * be called with '<\/script>' which would not match the original rule and
+    * so the generic tag rule would identify it as a tag.
+    *
+    * Pattern must only match prefixes, and if it matches a prefix, then that
+    * match is considered a token with the same style.

+DWORD  0x00000000     // data word 1
+DWORD  0xffffffaa     // data word 2
+DWORD  0x00000001     // data word 3
+DWORD  0x00ce0f20     // data word 4
+DWORD  ...            // next 'address word'</pre></blockquote><p>This stream of dwords does essentially this :</p><ul><li>write 0x00000000 into hw register 0x44</li><li>write 0xffffffaa into hw register 0x33</li><li>write 0x00000001 into hw register 0x22</li><li>write 0x00ce0f20 into hw register 0x11</li></ul><h4 class=CHeading>Special Cases</h4><p>There are a few additional operations besides filling hw registers necessary to drive the DAVE core.&nbsp; For example waiting for different busy signals.&nbsp; All special cases are encoded using address word entries equal to or above 0x80 (bit7 set).&nbsp; There will be no data words for such indices.</p><p>The behavior is unspecified if an address word contains &lsquo;gaps&rsquo; e.g. i3,0x80,i2,i1.&nbsp; If special indices are used, no normal index may follow after them in the same address word.</p><p>If the first index contains the special index 0xFF the following (second) index is interpreted as follows:</p><ul><li>bit 0 set :  display list end</li><li>bit 1 set :  wait for pipeline write to framebuffer cache complete then issue a full pipeline flush (texture cache and framebuffer cache) and wait for framebuffer cache write to framebuffer complete (necessary before flip)</li><li>bit 2 set :  wait for pipeline write to framebuffer cache complete (necessary before fb format change and alpha channel blending change)</li></ul></div></div></div>

+/**
+ * @fileoverview
+ * some functions for browser-side pretty printing of code contained in html.
+ * <p>
+ *
+ * For a fairly comprehensive set of languages see the
+ * <a href="http://google-code-prettify.googlecode.com/svn/trunk/README.html#langs">README</a>
+ * file that came with this source.  At a minimum, the lexer should work on a
+ * number of languages including C and friends, Java, Python, Bash, SQL, HTML,
+ * XML, CSS, Javascript, and Makefiles.  It works passably on Ruby, PHP and Awk
+ * and a subset of Perl, but, because of commenting conventions, doesn't work on
+ * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class.
+ * <p>
+ * Usage: <ol>
+ * <li> include this source file in an html page via
+ *   {@code <script type="text/javascript" src="/path/to/prettify.js"></script>}
+ * <li> define style rules.  See the example page for examples.
+ * <li> mark the {@code <pre>} and {@code <code>} tags in your source with
+ *    {@code class=prettyprint.}
+ *    You can also use the (html deprecated) {@code <xmp>} tag, but the pretty
+ *    printer needs to do more substantial DOM manipulations to support that, so
+ *    some css styles may not be preserved.
+ * </ol>
+ * That's it.  I wanted to keep the API as simple as possible, so there's no
+ * need to specify which language the code is in, but if you wish, you can add
+ * another class to the {@code <pre>} or {@code <code>} element to specify the
+ * language, as in {@code <pre class="prettyprint lang-java">}.  Any class that
+ * starts with "lang-" followed by a file extension, specifies the file type.
+ * See the "lang-*.js" files in this directory for code that implements
+ * per-language file handlers.
+ * <p>
+ * Change log:<br>
+ * cbeust, 2006/08/22
+ * <blockquote>
+ *   Java annotations (start with "@") are now captured as literals ("lit")
+ * </blockquote>

+    * all characters in sourceCode[index_n-1:index_n].
+    *
+    * The stylePatterns is a list whose elements have the form

+    *
+    * Style is a style constant like PR_PLAIN, or can be a string of the
+    * form 'lang-FOO', where FOO is a language extension describing the
+    * language of the portion of the token in $1 after pattern executes.
+    * E.g., if style is 'lang-lisp', and group 1 contains the text
+    * '(hello (world))', then that portion of the token will be passed to the
+    * registered lisp handler for formatting.
+    * The text before and after group 1 will be restyled using this decorator
+    * so decorators should take care that this doesn't result in infinite
+    * recursion.  For example, the HTML lexer rule for SCRIPT elements looks
+    * something like ['lang-js', /<[s]cript>(.+?)<\/script>/].  This may match
+    * '<script>foo()<\/script>', which would cause the current decorator to
+    * be called with '<script>' which would not match the same rule since
+    * group 1 must not be empty, so it would be instead styled as PR_TAG by
+    * the generic tag rule.  The handler registered for the 'js' extension would
+    * then be called with 'foo()', and finally, the current decorator would
+    * be called with '<\/script>' which would not match the original rule and
+    * so the generic tag rule would identify it as a tag.
+    *
+    * Pattern must only match prefixes, and if it matches a prefix, then that
+    * match is considered a token with the same style.
+    *
+    * Context is applied to the last non-whitespace, non-comment token
+    * recognized.
+    *
+    * Shortcut is an optional string of characters, any of which, if the first
+    * character, gurantee that this pattern and only this pattern matches.

+ * Title: Blit Functions
+ * BLock Image Transfer operations
+ *
+ * Blit's are special <Rendering Functions> to copy one rectangle part of
+ * the video memory into another part of the video memory.
+ * The operation could be performed using texturemapping and boxrendering as
+ * well, but the blit interface avoids setting and restoring all necessary
+ * context states.
+ *
+ * Texel-to-pixel mapping:
+ * Conceptually textures are seen the same way as a raster display: 
+ * Each texel is defined at the exact center of a grid cell.
+ * The driver maps the left border of the left-most texel to the left border 
+ * of the left-most destination pixel and the right border of the right-most 
+ * texel to the right border of the right-most destination pixel.
+ *
+ * Example: 
+ * Find below an example of resizing a source texture with filtering enabled.
+ * - A source image (3x1) is stretched to a destination rectangle (5x1).
+ * - A source image (5x1) is downsized to a destination rectangle (3x1).
+ * (see blit_mapping.png)
+ *
+ * Please not that the texel-to-pixel mapping implementation has changed 
+ * for the magnification case since D2 Driver version 3.10.

+ *   d2_mode_ai44     - colored, palletized 8bit per pixel, (4 bit alpha, 4 bit indexed RGB: see <d2_settexclut>)
+ *   d2_mode_i8        - colored, palletized 8bit per pixel (palette is used if d2_mode_clut is also set)

+ * Title: Context Functions
+ * Modify material settings
+ *
+ * Rendering attributes (like color, pattern, blendmodes) are stored inside a *context*.
+ * A context is a collection of material attributes and must not be mistaken with a device handle.
+ * A device handle (see: <Device management>) is the root of all process dependant data and is passed 
+ * as first parameter to every function. 
+ * This construct allows the driver functions to be reentrant in case of a multiple drawing engine units.
+ * 
+ * A device handle contains information about displaylists, framebuffers,etc... 
+ * Everything that the drawing engine will require. It also includes pointers to contexts.
+ *
+ * Each device has at all times pointers to three relevant context's :
+ *
+ *  selected context - This one is changed (written to) by the set commands shown below (see: <d2_selectcontext>)
+ *  solid context - Used as a source (read from) when rendering interior regions (see: <d2_solidcontext>)
+ *  outline context - Used as a source (read from) when rendering outlines or shadows (see: <d2_outlinecontext>)
+ *
+ * All three (selected, solid and outline) can point to the same context.
+ * Every driver function that starts with *get* or *set* will work on the currently selected context (with
+ * the obvious exception of geterror and getversion).
+ *
+ * There is always a *default context* that can not be freed by the application and is used for
+ * everything per default.

+ * Creating a device will never fail (sufficient memory assumed) but binding

+ * parameters:
+ *  flags - a bitfield containing flags
+ *

+ *  d2_df_no_dlist           - don't use a display list (slower single command mode)
+ *  d2_df_no_irq             - don't use an interrupt (slower polling used instead)
+ *  d2_df_no_fbcache         - disable framebuffer cache (attention: see note below)
+ *  d2_df_no_texcache        - disable texture cache (attention: see note below)
+ *  d2_df_no_dwclear         - disable double word clearing in d2_clear
+ *  d2_df_no_registercaching - don't use register caching
+ *  d2_df_no_blitctxbackup   - don't backup context data at blit for better performance; previous texture modes get lost and must be set again
+ *
+ * note:
+ *  Flags 'd2_df_no_fbcache' and 'd2_df_no_texcache' should only be used for debugging purposes.
+ *  Especially when multithreading is used, these flags must not be set different for devices which are bound to the same hardware instance through

+/*--------------------------------------------------------------------------
+ *
+ * Title: Render Buffers
+ * Renderbuffers (similar in concept to OpenGL display lists) are the main
+ * interface between driver and hardware.
+ *
+ * Issuing rendering commands to the D/AVE driver does not directly trigger
+ * a hardware activity but adds a set of commands to the currently _selected_
+ * Renderbuffer (see: <d2_selectrenderbuffer>).
+ *
+ * This buffer can be executed directly by the hardware. For best performance
+ * and maximum parallelism there should always be one renderbuffer executing
+ * while another one is being filled (double-buffered render buffers).
+ *
+ * The application can manage this on its own by using <d2_selectrenderbuffer>
+ * and <d2_executerenderbuffer> or make use of the utility functions and internal
+ * buffers (see: <d2_startframe> and <d2_endframe>).
+ *
+ * startframe / endframe:
+ * The recommended method using double-buffered render buffers is to use <d2_startframe> and
+ * <d2_endframe>. These functions use two internal render buffers in turn.
+ * The internal render buffers can be accessed by <d2_getrenderbuffer>.
+ * (start code)
+ * d2_startframe(handle); // --> start HW rendering of the previous frame (buffer a), switch to buffer b for all following render commands
+ *
+ * // ... now issue new render commands to buffer b while HW is rendering the previous frame from render buffer a ...
+ *
+ * d2_endframe(handle); // --> close render buffer b which has just captured all render commands, wait for HW to finish rendering of buffer a
+ *
+ * // may now propagate the rendered frame (from buffer a) to the display controller
+ * (end code)
+ *
+ * selectrenderbuffer / executerenderbuffer / flushframe:
+ * Render buffers can also be managed by the application. Use <d2_newrenderbuffer> to 
+ * allocate a new render buffer. To issue render commands a render buffer must be 
+ * selected by <d2_selectrenderbuffer>. A render buffer can then be executed by
+ * <d2_executerenderbuffer>. Before <d2_executerenderbuffer> can be called again
+ * the application has to wait for Dave to be finished by <d2_flushframe>.
+ * (start code)
+ * d2_selectrenderbuffer(handle, buffer);
+ *
+ * // issue render commands
+ *
+ * d2_executerenderbuffer(handle, buffer);
+ * d2_flushframe(handle);
+ * // propagate the rendered frame to the display controller
+ * (end code)
+ *
+ * Using a single render buffer:
+ * 
+ * Please note that when using just a single render buffer (no double-buffering) 
+ * the allocated buffer can not be freed as long as it is selected because the

+ * Render a polygon from a triangle fan
+ *
+ * When rendering connected structures where all triangles share a common vertex a triangle fan
+ * can be used instead of a triangle list (<d2_rendertrilist>). The advantage is that for every
+ * triangle except the first one only one additional vertex has to be specified.
+ * The other two vertices are reused from the previous triangle and the common base vertex.
+ * See diagram for explanation:
+ *
+ * (see trifan.gif)
+ * Triangles rendered from the order given above are :
+ * - 1,2,3
+ * - 1,3,4
+ * - 1,4,5
+ *
+ * Internal edges are automatically flagged as shared but you can still specify a flag
+ * for each triangle in order to define additional shared edges.
+ * There is one flagbyte per triangle. If no additional sharing information is required
+ * you can pass NULL for the 'flags' pointer.
+ *
+ * The first triangle must be defined in clockwise order (others will then be clockwise as well).
+ *
+ * parameters:
+ *   handle - device pointer (see: <d2_opendevice>)
+ *   data - pointer to an array of 2*count+4 d2_point values (count+2 x,y pairs)
+ *   flags - pointer to an array to count bytes containing edgesharing flags or NULL
+ *   count - number of triangles
