Shader preview job localizes material without referencing it as a user,
so don't need to unreference itself as a user from this material.
Added BKE_material_free_ex function which could skip user dereferencing.
This also removed old hack with mtex users.
Movie cache is using global memory limitor, which isn't thread safe
in some of operations, so it required to add mutex around limitor
operations in movie cache.
It's probably could be solved in a way with less locks involved
bu using different limitor for different areas (like use own limitor
for clips, own limitor for sequencer and so), but that wouldn't be
so easy to control overall memory usage.
in some cases, in particular when the the edge loops were not planar.
Now rather than finding the shortest distance between two vertices, one from
each edge loop and using that as a starting point, it now finds the smallest
sum of distances between all vertex pairs that would be connected.
- Move color management settings to scene, so it's now clear for
all areas (such as compositor, sequencer) which settings to
use for display buffers
- Currently removed per-editor color management settings. It could
be nice to have them, but they don't fit nicely into overall
pipeline and could be added as a override settings for display
only later.
- Make sequencer working in space defined by sequencer_workspace
role in OCIO configuration file.
If this role is not set, sequencer will fallback to legacy sRGB
Gamma 2.2 space.
Currently use vd16 color space for sequencer. Not sure what exactly
this color space is, but it's pretty close to SPI Film view and
it's still invertable.
- Sequencer will now output linear float buffers, not color managed
float buffers.
Before this sequencer used to output float buffers in sRGB space,
which was sequencer's working space. Now it can not output buffers
in this space since other areas are not aware of this space.
This also makes it's consistent that all float buffers in Blender
are in linear space.
- When saving render result into byte file format scene's display
transform would be applied on this buffer.
When saving files from image editor, there'll be a display
transform settings which are default set to scene's settings but
could also be overwritten.
Additional details are there (would be extended soon):

After 2.63 there was a bugfix to take object scale into account for the duplicated
objects, but this breaks compatibility on earlier files. Now there is an option to
control if the scale should be used or not.
Scale is used by default on newer files, and not used on older ones.
