This way it is possible to have single threaded depsgraph but threaded other areas
which is handy for torubleshooting.

We're currently only supporting save to a default format color space, which
makes it a bit tricky to prevent ImBuf from being changed.
For until when saving to a custom colorspace works we'll just reload image
if the space changes.
Previously we don't merge material cached list, it create dangling pointer and memory leak.
Now we merge material cache list during the scene merge, and remove material in this list during the library free.

Issue here is that intermediate result was clipped as an optimization in
such nodes and thus not converted to the correct type properly. Now only
clip those values if types match.
This keeps both the optimization and the conversion. I looked at
converting uniform types always but it's more involved to compare types
at conversion time for such links because the type was getting
overridden during link duplication.
In certain configurations (for example when start resolution is set to small
value for background render and progressive refine enabled) number of tiles
might change in the tile manager. This situation will confuse progressive
refine feature and likely cause crash.
We might also add some settings verification in the session constructor, but
having an assert with brief explanation about what's wrong should already be
much better than nothing.
It was possible that two threads will start calculating proxy group's inverted
matrix and store it in the object itself. This isn't good idea because it means
some threads might be using partially written matrix.
Previously it was very easy to run into situation when two objects are sharing
the same materials with drivers which will cause threading access issues.
This actually only needed for the old depsgraph, but since it's still the one
we're using by default we'd better solve this issue.
There were some reported data race conditions in the python interpreter which
seems to be rather valid.
Surely this is not very pretty solution, but it might solve some annoying bugs
related on threading.
For a long time this function was only intended to be used from the main thread,
but since out implementation of parallel range (which is currently only used by
mesh deform modifier) we might want to switch to threaded alloc from object
update thread.
Now we're using spinlock around the check, which makes the code safe to be used
from all over the place.
We might consider using a bit of atomics operations magic there, but it's not so
much important for now, this code is not used in the performance critical code
path.
Fix for T36639 caused all path changes to reload (which could loose user content).
Change behavior:
- Only reload data when a flag is explicitly passed
(currently only used by Find Files operator)
- Don't reload images which have been painted onto and not saved (dirty flag set).
