An index stored in Alembic wasn't used. Often this index is a no-op
(i.e. index[n] = n), in which case the result was fine. However, when it
isn't, it caused issues.
There was a fake cyclic dependency happening when node of node tree is driving
another node of the same tree.
This is related to T53794, but more fixes is needed here.
This patch fixes a 32-bit overflow that occurs on 64-bit systems due to a numeric literal being treated as 32-bit.
This patch allows for the generation of images that occupy more than 4GB of RAM, which previously caused a crash.

Brushes themselves are still affected by the mask, but the viewport is not
showing the mask. This way it's easier to see details while sculpting.
Studio request by Julien Kaspar
Adds the code to get screen size of a point in world space, which is
used for subdividing geometry to the correct level. The approximate
method of treating the point as if it were directly in front of the
camera is used, as panoramic projections can become very distorted
near the edges of an image. This should be fine for most uses.
There is also no support yet for offscreen dicing scale, though
panorama cameras are often used for rendering 360° renders anyway.
Fixes T49254.

For experimental options, outside the scope of typical preferences.
While templates are developed we might want to make changes
to behavior which aren't fully compatible with typical work-flows.
Instead of mixing these options in with current preferences
expose separately (we could even force disable them when templates
aren't int use)
This can be enabled in the Film panel, with an option to control the
transmisison roughness below which glass becomes transparent.

The offscreen dicing scale helps to significantly reduce memory usage,
by reducing the dicing rate for objects the further they are outside of
the camera view.
The dicing camera can be specified now, to keep the geometry fixed and
avoid crawling artifacts in animation. It is also useful for debugging,
to see the tesselation from a different camera location.

Use the libraries if they exist in ../lib/linux_x86_64 or similar, so
that you can run "make deps && make full" to get a full static build.
Note that install_deps.sh is still the only officially supported way to
build Blender dependencies on Linux, but this may be useful to some.

Remove the critical OMP sections used to protect mem allocation.
First one can be done in a separate loop before main, parallelized one.
Second one only affect 'private' data, so we only need to ensure
guardedalloc thread safety is enabled.
This is committed as separated step to ease troubleshooting in case
bisecting becomes necesary.
Gives about 40% speedup of object which has simple-ish deformation applied
on top of subdivided mesh.
This might easily happen with single character animation.
Helps in cases of not very complex scenes and lots of system threads available.
A bit hard to measure change on it's own, it works best with the upcoming
changes and gives measurable improvements.
Mutex is now local to particular CCGDM, and guarding edge hash which is only
used by a single function only. There is no need to acquire read lock after
edge hash was created.
