Apparently this is the result of some sloppiness during 2.5 project and since then it confused people who were trying to understand the area-region relation (myself included).
Sorry if this causes merge conflicts for anyone, but at some point we really had to do it :/
C++ structures might be rather big and passing them by value is not really
optimal. There should be no functional changes apart from better memory
access pattern when synchronizing huge scenes to Cycles.
Restore fixed function lighting code for now and control use of GLSL shader
with a variable, make light types more clear, reduce state changes, some other
minor tweaks.
Issue was with datablocks which names would include '/', new filebrowser filelisting code
would cleanup the entire filepath, hence giving invalid filename in this case.
That 'path separator in ID names' bit us already in lib/datatype/datablock separating func,
this is really stupid to allow that in something handled as a filepath imho, but well...
Note: would have break the same under *nix with '\' char.
Keep index using the outer scope for GHASH iter macros,
while its often nice, in some cases to declare in the for loop,
it means you cant use as a counter after the loop exits, and in some cases signed/unsigned may matter.
API changes should really be split off in their own commits too.
GPU_buffer no longer has a fallback to client vertex arrays, so remove
comments about it.
Changed a few internal structs/function interfaces to use bool where
appropriate.
Use for-loop scope and flexible declaration placement. PBVH does the
same thing but needs ~150 fewer lines to do it!
The change to BLI_ghashIterator_init is admittedly hackish but makes
GHASH_ITER_INDEX nicer to use.
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.
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.
