Overlay Mode: Fix infront depth sorting

This is an improvement to 2.81. In front objects and extras are correctly
depth sorted.

The approach is to share an in-front depth buffer between all engines
so that workbench fill it with the infront objects depth. Then the overlay
engine can use it again to draw in front objects overlays correctly
occluded by the other "in front" objects surfaces.

GPencil: More tweaks to UI panels

GPencil: Display two colors only for required Tools

GPencil: Add Add/Sub Brush color to Display Panel

Merge branch 'master' into temp-graph-select-changes

GPencil: Use Standard Falloff curves for Sculpt/Weight Paint

As the tools are bruhes, we can use the standard Curves.

Overlay Engine: Improve In Front pass ordering

This does not fix all the issues. For instance extra's are always drawn
occluded.

GPencil: Cleanup - Reorder Make list

GPencil: Rename Panel

Add threaded handling of finalize callbacks for parallel range pool.

As suggested by @sergey in review comments, thanks.

Thhis will add a additional speed-up benefit to using those pools when
finalization computations are not trivial.

Squashed UDIM patch (D3509) another time

Apparently the buildbot process changed and it builds the latest branch commit now.

Revert "Squashed UDIM patch (D3509) once again"

This reverts commit 4e90f53dbcf0220f2daa25bb8d1b389bee1bb8de.

Squashed UDIM patch (D3509) once again

Merge branch 'master' into experimental-build

Replaced `#include "../usd.h"` with `#include "usd.h"`

Also `include pxrTargets-release.cmake` when harvesting dependencies

Added & corrected GPL license blocks

Mantaflow: Small adjustments to surface-distance parameter

Better default values

USD: Build improvements

- Removed the `USD_PATH` variable, expose `USD_ROOT_DIR` from `FindUSD.cmake`
instead.
- Properly call `find_package_wrapper(USD)` from `platform_unix.cmake`.
- Added USD files to `harvest.cmake`.
- Removed `external_python` from USD dependencies, as we don't use USD's
Python interface.
- Removed Fink and DarwinPorts support.
- Enable USD in `blender_full.cmake`
