reported as [#29376] BMESH_TODO: remove tessface CD_ORIGINDEX layer
for a single mesh there could be 3 origindex mappings stored, one on the polygons and 2 on the tessfaces.
(CD_POLYINDEX and CD_ORIGINDEX).
as Andrew suggests, now tessfaces (which are really a cache of polygons), using origindex to point to polygons on
the same derived mesh, and polygons only store the original index values.
Text object render error.
Issue was caused by FLT_EPSILON being used to check for zero-sized faces, for
getting a reliable normal of front/backfaces of polygons. This value is too
small, giving occasional bad looking faces.
In other parts of code FLT_EPSILON10 was being used, that works much better.
Note for the future: here using doubles internally would be advised.
Full Sample Antialiasing render gave fireflies with halos - especially on edges of polygons.
Reason was FSA exception case in code, using uninitialized color array.
Probably these fireflies were hunting us already for many many years.
Render error.
Particle systems that duplicate group instances were setting the wrong
layer to the instanced objects, the correct layer is the particle system
itself - as being shown in the viewport correctly already.
Old report from May 2011 :)
- define array sizes for functions that take vectors.
- quiet some -Wshadow warnings.
- some copy/paste error in readfile.c made it set the same particle recalc flag twice.
That was an old check whether tiled EXRs are used during rendering
since version 2.42 where there indeed was a special check for tile
size in EXR tile code.
Now it seems EXR could handle tiles with non-equal size and no
extra tile size check happens for EXR. Anyway EXR tile initialization
happens after initparts, so clamping size in initparts should be
safe for EXR tiles as well.

There was a missing check for whether color management enabled or not when
converting byte textures to linear space.
This commit also fixes wrong texture preview rendering, which was applying
sRGB transform twice, making procedural textures bright. This will make
float textures being previewed dark (in a linear space) but that's how it
used to behave in pre-OCIO color management.
Generated and UV coordinates from the duplicator of instance instead of the
object itself.
This was used in e.g. Big Buck Bunny for texturing instanced feathers with
a UV map on the bird. Many files changed, mainly to do some refactoring to
get rid of G.rendering global in duplilist code.
Made it so viewport will disable color management if display device set to None.
This solves couple of regressions, mainly related on old BGE files and made
None display behave exactly as old color management disabled.
