This was necessary for a new action which uses a message box to display information but it's meant to stay open while you interact with the rest of the UI.

The intent of `mesh->bslsp` was really `!mesh->bsesp` and to ever support shaders on Oblivion/FO3 this change is needed as those won't be BSLSP either.

Show which blocks reference this one

For FNV and later, convert CLS to LS, and for FO3 and earlier, convert LS to CLS.

Merge multiple CVS into a list shape.  Take the entire transform into account for CVS.  Support BSTriShape.

Also synced to XML.

Added token replacement, support for `onlyT`/`excludeT` by simply aliasing back to the `cond` version for now.

At least acknowledge bitfield tags for now, but do not do anything with them other than alias them to their storage type.

Support for the BSStreamHeader reorganization in Header.
Renamed TEMPLATE and ARG tokens.
Removed userver and userver2
Do *NOT* support int64/uint64 yet other than the type map so that nifxml won't error.

Supported more BA2 texture formats.  Made file filter case insensitive.

Some platforms were trying to choose ANGLE instead of OpenGL.

Rendering support added for some versions of NiStencilProperty could crash.

nifxml does not have sufficient means to deal with short circuiting of blocks based on a string value.

Also some general fixes.

Very minimal rendering and shader support for new Lighting and Effect shaders.

For Lighting, mostly correctly uses the new PBR pipeline with metallicity/reflectivity and an external cubemap (currently 1 hardcoded).  New emissive masks and AO masks are also used to various degrees.  AO mask is used for specular occlusion.

Uses sRGB framebuffer when needed.  Does not add support for sRGB textures in SSE and FO4 NIFs.

Resource collisions between Fallout 4 and Fallout 76 were severe due to a vastly different asset pipeline while maintaining the same filenames.  Technically resource collisions happened with Skyrim and Skyrim SE too, but the vanilla files were largely identical.

The game manager associates texture and material lookups to a particular game, based on the NIF version.

This does mean that Fallout 3 and Fallout NV are considered the same meta-game and lookups for either game's files will be done in both games' paths.

A "game mode override" is planned to address this.

The sRGB framebuffer being used for some versions caused glClearColor as well as glColor3/4 etc. to be incorrect.

Re-scanning the latest files showed a missed `NO_EXPOSURE` usage. Unsure if there since release or if added.  `LOD_OBJECTS` was also missing in NifSkope but was already present in nifxml.  Outside of BTOs, one single NIF uses `NO_EXPOSURE`.

As of August these are the only used shader flag CRCs.

Since editing of this version will not be supported, unused flags will continue to be excluded.

The automatic stringification for BSVertexDesc got lost in the refactor, when it was made into a bitfield which is treated as an aliased type like enum/bitflags and thus is mostly treated as uint64.

Return pointer from Message helpers when needing to customize the behavior.

Added a log message function directly to the model which allows any function with a nif pointer to support both UI messages and the file checker output.  For example, functions that are sanitizers (run on save) and used to output information in the file checker.

Renamed XML Checker to File Checker since apparently nobody realizes the window even exists.

Added basic value checking.  Currently arrays are not traversable except for the first item of the array.  Compounds can be descended through the slash syntax used elsewhere in the program.

Added a few basic error checkers that run on Sanitize as well as during file checking.  They were only done upon user request so they are not very thorough.

Files that error during header read no longer fail silently.  Also added an option to only read the header and the BSStream version is now printed with the filename.

Older Bethesda NIF versions (Oblivion, FO3) can use bhkNiTriStripsShape as a Havok shape which is relatively easy to import to from a file.

Switched back to absolute paths for game folders, fixed auto detection in the UI and at initializing of said paths.

The idea was to show only relative paths for both folders and archives if they were under the install path as this would tidy up the UI.  In practice, supporting both relative and absolute (outside of game install) paths in the same list in the UI and registry is not worth the effort.

Name simplification, general cleanup.

Closes #30

Also, move alternative file extensions checkbox to main Games tab.

Other Games fallback search will look a final time in all listed resources in Other Games if no file is found for the game's own resources.

Also early accept

Only run for Bethesda NIFs as described in the class comment.  Support BSTriShape based shapes.

…project file builder

…s) to about a quarter of the former speed

- Instead of a tiny 512x512 window, open the UV editor maximized and more zoomed in
- Changed the window's type from Tool to Window. This shows the editor in Windows task bar and adds maximize/minimize buttons to its title bar.

…makes the code more readable.

- Fixed some compiler warnings.
- Minor refactoring here and there.

…nif data.

Primary goal: making sure that the properties of internal classes are reset on each update. That should fix some bugs happening when a nif is changed in NifSkope.
Secondary goals: optimizations and better structure of the code.

Bonuses:
- Replaced NifModel::getUserVersion2() with new NifModel::getBSVersion(). The latter has a better name and returns the version from cache (created once, on file load) instead of reading it from the header every time.
- Added static NifModel functions for very common casts of QModelIndex to NifModel.
- Replaced many "protected property + basic getter and setter" in Property classes with just "public property" to simplify the code.
- Deleted some obsolete/unused properties and functions, mainly in IControllable family of classes (nif nodes and properties).
- Fixed some compiler warnings.
- Better naming, minor optimizations, cleanup here and there.

Also fixed the wireframe flickering on the same shapes with alpha.
Skyrim SE or newer nifs used to be especially prone to these bugs.

Added pre-allocation of the result QVector.

2 big(-ish) classes sharing a single glmesh file has become unwieldy.

Main goals of the whole model refactoring:
- For NifItem and *Model (BaseModel, NifModel, etc.) methods with a QString parameter provide QLatin1String and 'const char *' overloads. QLatin1String("foo") is much faster than "foo" with its under-the-hood conversion to QString because in Qt 5 QLatin1String("foo") could be done at compile time. And this will make something like reading Skyrim SE shapes several (4 to 8) times faster.
- For *Model methods working with QModelIndex child items provide convenient overloads to work with 'NifItem *' instead. Overall, gradually migrate from using QModelIndex to 'NifItem *', at least on low level, to avoid back-and-forth conversions between QModelIndex and 'NifItem *' and to simplify the code overall.

Bonuses in this commit:
- NifItem: name(), type(), ... getters now return 'const QString &' instead of QString, to avoid wasting resources on creating a QString copy when it's not needed.
- NifItem: new hasName and hasType methods as a replacement for 'name() == "foo"' and 'type() == "foo"' ('const char *' overloads - for performance (see main goal #1), QString and QLatin1String - for uniformity).
- NifItem: new get<T> method as a shortcut for this->itemData.value.get<T>().
- NifItem: static versions of get<T> and getArray<T> methods, with a nullptr check for the item.

…d nullptr check.

…ils...") if it has been called before in this session and that message box has been closed with "X" button instead of "OK".

Bonuses for Message::append:
- Set the minimum width of the message box to about a quarter of the screen resolution.
- The details are shown by default now (saves one click on "Show Details...").
- For each main window of NifSkope, its own message box is now created instead of dumping messages from all main windows into a single box.

- NifItem: Reworked cached data (row index, child link items) to make it more reliably updated.
- NifItem: Added a lot of shortcut functions to its itemData.value methods.
- BaseModel/NifModel/KfmModel: Expanded and standardized overloads for various item getters, setters and checkers. With putting more emphasis on working with NifItem * instead of QModelIndex and with some string tricks (const char * -> QLatin1String), it should result in a smaller and faster code overall.
- Many NifItem getters and setters now show a message box if they detect a problem instead of silently returning a default value or false. This is more for debug purposes, to catch and polish any rough spots in the code.
- Got rid of a bunch of repeating code (for example, in item condition evaluation).
- Gave some functions better names (for example, updateArray -> updateArraySize).

Manual merge for niftools#230

Mainly meant for when there are 0 errors, so that it is clear there were no errors.

- Changed C++ standard version to 20 (from 14 and "latest").
- Changed output file template to vcapp (Visual Studio Project).

This is required since Qt 5.15 for the "Windows" UI themes to work properly.

- Fixed undefined M_PI and other C++ math constants once and for all. Apparently, including math.h is not enough, _USE_MATH_DEFINES macros also must be defined. Solved by adding _USE_MATH_DEFINES to NifSkope.pro.
- Added functions for converting radians to degrees and back.
- Minor refactoring of Vector2, Vector3, Vector4 classes (improved precision of normalize() by removing a redundant multiply operation, added toString() method, minor optimizations and fixes).

Note: if you don't update the project file by (re)generating it from NifSkope.pro, you must add _USE_MATH_DEFINES macros by hand for it to compile. In Visual Studio 2022 it's done in the project's properties -> Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions.

by limiting the max. number of detailed text lines (error lines) in a message box to 50.

…rom Qt on Message::append

by moving msgBox->setDetailedText(...) after msgBox->show().
Also registration for "OK button pressed" event was moved before msgBox->show(), just to be safe.

…NiNode in "Show Nodes" + "Show Axes" mode

because it's a Matrix not a Quat.

NifItem class:
- Replaced "type" in the name of the string type functions (type(), hasType, setType) with "strType" (strType(), hasStrType, ...) to make it clearer that this is not about the numerical type of the item's value.
- Replaced "temp" in the template functions (temp(), setTemp) with "templ" (templ(), setTempl). "Temp" made me think it has something to do with "temporary".
- "Value" functions got shorter or clearer names. For example, valueIsCount became isCount, valueToCount - getCountValue, valueFromCount - setCountValue.
- Deleted most of the static functions that checked for item == nullptr. No point to bloat the code for just 0 to 3 uses for those static "mirrors".
- Added isArrayEx() which checks if the item is an array or its parent is a multi-array (same check as in the old BaseModel::isArray(const NifItem *)).
- Added repr() function that returns string representation of the item ("NiTriShape [0]\Vertex Data [3]\Vertex colors").

BaseModel class:
- Renamed isArray(const NifItem *) method to isArrayEx to show that it and isArray(const QModelIndex &) make different checks.
- "type" and "temp" methods followed suit of their cousins from NifItem.
- Fixed "look by child name" overloads of getItem ignoring reportErrors arg if the child name is a path with "\\".
- If updateArraySize methods fail to find the array by its name, they will report it.
- Added a string representation function and a couple overloads of reportError for a QModelIndex.

NifModel class:
- Fixed loadHeader failing to reset "BS Header\BS Version" field because of the preceding reset of "User Version" field making its condition invalid.
- If setLink or setLinkArray methods fail to find the item by its name, they will report it.
- Added some new stuff to the map of array singular pseudonyms.
- Added a couple of quality of life function for working block numbers/links.

…ot pass mesh version or block type checks, even when "Show Non-applicable Rows" option is on.

This makes the views much cleaner by hiding all the fields that are irrelevant to the current mesh (its version) or the current block (for example, doubled "Triangles" and "Vertex Data", or always read-only "Shader Type" in BSTriShapes).

…kope's ones.

It used to stay in the middle of the screen even when you switch to your browser or any other app, covering everything underneath it.
Now Settings will block only NifSkope's windows and disappear if you switch to another app.

It used to stay on top always (even if you switch to another application), but did not block input to the parent mesh window.
Now NifBlockEditor stays on top of the parent window only and blocks input to it.

…Details"

- Added pseudonyms for almost 200 arrays. All the arrays from nif.xml ( https://github.com/niftools/nifxml/tree/develop version) are now covered, with the exception of arrays that don't need pseudonyms or have too generic names ("Data", "Value", "Unknown", ...).
- Multi-arrays (2-level arrays; e.g., UV Sets, Vertex Weights) got their own pseudonym subsystem, with a different logic.
- Binary arrays are now ignored because it's always a single item with a "X bytes" value.
