with material ambient zero broke backwards compatibility too much. The behavior
to have ambient zero affect things even if it is not used as a factor does not
make much sense but keeps things compatible. Now instead fixed the use of
uninitialized memory.
Currently supported passes:
* Combined, Z, Normal, Object Index, Material Index, Emission, Environment,
Diffuse/Glossy/Transmission x Direct/Indirect/Color
Not supported yet:
* UV, Vector, Mist
Only enabled for CPU devices at the moment, will do GPU tweaks tommorrow,
also for environment importance sampling.

Detect feedback loop and do not bake to images detected in this loop and show
nice warning message in such cases.
It's a way which wouldn't overcomplicate code trying to duplicate images and so
without real benefit.
Issue was caused by incorrectly set PTS value frames came form Scene strip renderer.
This value used to be calculated from RenderData current and start frame which
lead to non-uniformuly counting which totally confuses encoder.
Switch append_avi and append_ffmpeg to use current frame from rendering scene
(which was already passing to this functions and was used mostly for logging)
and start frame of rendering scene (it's new parameter added). This allowed to
calculate correct PTS value easily and get rid of global static sframe variable
in writeavi.c file.
This commit extends limit of ID and objects to 64 (it means 63 meaning
characters and 1 for zero-terminator). CustomData layers names are also
extended.
Changed DNA structures and all places where length constants were hardcoded.
All names which are "generating" from ID block should be limited by MAX_ID_NAME-2,
all non-id names now has got own define called MAX_NAME which should be used all
over for non-id names to make further name migration stuff easier.
All name fields in DNA now have comment with constant which corresponds to
hardcoded numeric value which should make it easier to further update this
limits or even switch to non-hardcoded values in DNA.
Special thanks to Campbell who helped figuring out some issues and helped a lot
in finding all cases where hardcoded valued were still used in code.
Both of forwards and backwards compatibility is stored with blender versions newer
than January 5, 2011. Older versions had issue with placing null-terminator to
DNA strings on file load which will lead to some unpredictable behavior or even
crashes.
A better solution would be to mark all function in openexr_multi.h as forceinline or static, but this change just fixes it to work for the reason trunk works: the header defining the stubs is only needs to be included in one .c file
Sequencer render context should be as large as the whole frame when rendering
using border without clipping.
Can be implemented in more clear way but it'll require more global refactoring.
For premultiplied alpha images, this makes any color space conversion for the image
or render output work on color without alpha multiplied in.
This is typically useful to avoid fringing when the image was or will be composited
over a light background. If the image will be composited over a black background on
the other hand, leaving this option off will give correct results.
In an ideal world, there should never be any color space conversion on images with
alpha, since it's undefined what to do then, but in practice it's useful to have
this option.
Patch by Troy Sobotka, with changes by me.
