In gpu lib:
- GPU_glsl_support() always returns true
- internal cleanup & comments
Outside gpu lib:
- remove check from various code, remove the “else” path
- sprinkled a few C99-isms
We can remove GPU_glsl_support() when BGE stops calling it.
It uses edge extrapolation code from Gimp's antialias plugin now,
which has advantage of giving symmetrical results, which makes it
possible to add two antialiased ID masks and have a constant 1.0
all over the frame. But has difference from the old implementation
because it uses 3x3 matrix only, which doesn't give so much smooth
looking edges. Perhaps it's not so bad, since if edges are really
need to be smooth one might use Blur node.
Another advantage is that the node is now nicely threaded.

This makes it possible to use scenes as a kind of
multi-user meta-strip (with their own time).
Currently this supports rendering & drawing nested strips,
but no convenient way to tab-enter into a scene strip.
When a user tries to load a non-existing blend file from the CLI, the path
is set and Blender acts as if it is loaded. This allows the user to create
a new file by typing 'blender filename.blend' and then saving. This
behaviour is common in other tooling, such as vim and Mypaint.
Blender's current behaviour (print an error message and open the default
scene) doesn't make much sense. It ignores the filename passed on the CLI,
whereas with this patch that filename is actually remembered, and used when
saving.

The issue was caused by possible use of object->derivedFinal from the render
thread, The patch tries to eliminate (or at least minimize, huh) amount of
access to the derivedFinal of a source object. It's still possible that in
the case of particle source derived mesh will be still unsafely used, but
with the patch applied we can easily change runtime part of the code and
cache derived mesh on the preparation stage.
Some ideas for the future:
- Check whether cache() was called on the point density node when calling
calc().
- Cache derivedMesh in the runtime part of point density node to avoid
possible remained thread conflicts.
- NULL the runtime part of the node on .blend load

This mimics OpenMP's 'firstprivate' feature. It is sometimes handy to have some persistent local data during a whole chunk.

Input array length is implicitly set at link time, based on the geometry
shader's layout. Specifying the wrong value here is an error; specifying
no value is the same as getting it right. (inspired by a recent codegen
change)
the paint cursor drawing when a stroke is underway; this information is
already available from the stroke itself.
Should improve performance when "show brush" is enabled (which is
always, for sane people). Finding an intersection is not always cheap,
especially on heavy meshes.
Cudos to the dyntopo test thread for the report and the sculpt love :)
yet another bug introduced by recent shadowing changes -- q and r CCG arrays
were overwritten by the temporary evaluation because the code was changed to
use global pointers instead of the local ones.
Naming of the variables could be changed to be a bit more accurate.
This is sort of extension of existing Use Environment option which now allows to
disable AO on the render layer basis.
Useful in cases like disabling AO for the background because it might make it
too flat and so.

This patch allows the game engine to keep running while performing things like PNG compression and disk I/O.
As an example, my crowd simulation rasterizer saves a screenshot for every frame. This now takes up 13 msec per frame, which was 31 msec before this patch. Effectively, it allows the simulation to save every frame and still run at 60 FPS.

Formatting of generated GLSL code:
- attribute/varying for version 120
- in/out for version 130+
- minor cosmetic stuff
Tested working on Windows 10, GL 4.3.
Fix GLSL version & geometry shader support query to consider core vs
compatibility.
All shaders need to be compatible with each other, and for now that
means GLSL 120. For drivers that support compatibility profiles, choose
the highest available (up to 150). If only core profile is supported,
max out at GLSL 130.
Several changes. Tested working on Windows 10 GL 4.3 and MacOS 10.11 GL
2.1.
- document extensions used in this file
- some simple ARB/EXT suffix deletion
- stop checking for pre-2.1 features — they’re available!
- convert old ARB shader API to the one adopted in GL 2.0
- remove checks for old (pre-R600) ATI cards
- choose GLSL version at runtime, between 1.2 and 1.5
- prefer GLSL 1.5 for geometry shaders, fall back to
EXT_geometry_shader4 if needed
