Caused by an -unneeded now- fix for opensubdiv. Code caused the vertex
colors to be uninitialized. Thanks to Sergey for confirming that initial
issue is no longer a problem.
- wasn't checking subframe to see if the scene needed to be re-evaluated.
- unneeded int/float conversion storing original frame.
- moved cleanup block into one place to avoid confusion.
Basically filtering was happening twice, first time by applying weights of EWA
filter itself and then by applying subpixel offset while reading pixel values.
Primary goal of this commit is to fix an annoying issue - when processing and saving .blend
files in background mode you lose their thumbnails, since it can only be generated with
an OpenGL context.
Solution to that is to read .blend thumbnail while reading .blend file (only done in background
mode currently), and store it in Main struct.
Also, this lead to removing .blend file reading code from thumb_blend (no need to have doublons).
We now have a small interface in regular reading code area, which keeps it reasonbaly light
by only reading/parsing header info, and first few BHead blocks.
This makes code reading .blend thumbnail about 3 to 4 times slower than previous highly specialized
one in blend_thumb.c, but overall thumbnail generation of a big .blend files folder only grows
of about 1%, think we can bare with it.
Finally, since thumbnail is now optionally stored in Main struct, it makes it easy to allow user
to define their own custom one (instead of auto-generated one). RNA API for this was not added though,
accessing that kind of .blend meta-data has to be rethought a bit on a bigger level first.

Issue was caused by blender internal accessing data from DNA during rendering.
There's no simple solution to make stuff thread safe, so for now simply restart
rendering on frame update.
This is more like a workaround to prevent obvious cases fail, but in theory
if some other area will start updating object for subframes blender will
crash again.
Perhaps proper way to solve this will be to copy objects for subframe updates.
The issue was in fact caused by both preview and viewport renderers affecting
on the default material, conflicting with each other.
Preview render doesn't really need default material, so we can safely skip it's
initialization in the render pipeline for preview rendering.
Don't force re-distribution of cached particle systems, this doesn't
cause actual evaluation of particles and there was a reason why particles
are baked actually..
It was possible to navigate into an unused temp screen
(using Ctrl+Arrow keys), but there was no way to navigate back out.
Now Ctrl+Arrows skips temp screens, and remove the ability to navigate away from a temp screen from RNA.
