• Rewrite tracediff in C++:

• Add some common command-line options:

  Most commands acting on a trace accept the following common options:

  --calls=[RANGE]       Operate only on calls with index numbers within
                        the specified range.
  
  --frames=[RANGE]      Operate only on frames with index numbers within
                        the specified range.
  
  --functions=[REGEXP]  Operate only on function calls which have a
                        name that matches the given regular expression.
  

  A [RANGE] can be any of the following:

   Example    Description
   -------    -----------
   4          A single number specifying a single call or frame.
   
   10-20      Two numbers separated by '-' (FIRST-LAST) specifying a
              range of consecutive calls/frames from FIRST to LAST. If
              either of FIRST or LAST is omitted, the first or last
              call/frame index in the trace will be used.
   
   1-100/5    Either of the above range specifications followed by '/'
              and a number (INTERVAL). This specifies the inclusion of
              only each INTERVAL call/frame within the range. For
              example, 1-100/5 species frame 1, frame 5, frame 10,
              ... up to frame 100.
   
   4,10-20/2  A comma separated list of any of the above range
              specifications, specifying the union of the ranges.
  

• Add some trim-specific options (--every={draw,framebuffer,frame})

• Add an "apitrace bisect" for trimming down a trace based on user input at each stage.

• Add an "apitrace git-bisect-helper" for calling from git-bisect.

• Add a histogram feature to show the number of calls to each GL function. Sort the output from most-called to least-called.
