Things To Do
============
(in no particular order)
Tracing
-------
* Allow clamping to a GL version or a number of extensions.
* Trace multiple threads:
* `GetCurrentThreadId()`
* `pthread_self()`
* Put zlib (de)compression in a separate thread.
* Trace TSCs
* Trace window sizes somehow
* Allow to distinguish between the calls really done by the program, vs the
fakes one necessary to retrace correctly.
* Start tracing on demand (e.g., key-press, or by frame no), emitting calls
that recreate all current state.
* Add option to include call stack frames in the trace.
* Trace the internal GL calls done by GLU on Mac OS X & Windows.
Retracing
---------
* Use visuals that best match those used in the trace; specially auto
detect single/double buffer visuals.
* Respect multiple context sharing of the traces.
* Support multiple threads
* Leverage ARB_debug_output where available.
* D3D support.
GUI
---
* Timeline view.
* Visualize meshes in draw commands.
* Breakpointing and step-by-step debugging.
Other
-----
* Side-by-side trace diffing; either as a separate tool on or the GUI.
* Ability to extract just a single frame from a trace, and all previous calls
that contributed to it:
* via a state tracker (i.e., knowledge of how calls affect the state);
* or by leveragine retrace, dumping the calls to emit all state at beginning
of the frame.
