Merge branch 'master' into soc-2020-io-performance

Initial raw liboverride-dedicated view in the Outliner.

Disclaimer: this is merely a copy of the Libraries (aka blend file)
view, with some minor tweaking.

Pose Library: add `POSELIB_OT_apply_pose_asset` operator

Add operator `POSELIB_OT_apply_pose_asset` that does the same as executing
(instead of invoking) `POSELIB_OT_blend_pose_asset` with
`blend_factor=1.0f`. This will replace the Python equivalent in the
pose library add-on.

Pose Library: allow blending in flipped poses

Allow a flipped pose asset to be blended into the current pose.

Cleanup: Rename `POSELIB_OT_blend_pose` to `POSELIB_OT_blend_pose_asset`

Rename the pose blending operator to `POSELIB_OT_blend_pose_asset`, so that
we can make an operator `POSELIB_OT_apply_pose_asset` without colliding
with the old `POSELIB_OT_apply_pose` operator (from the current pose
library system instead of the new one).

No functional changes.

LineArt: Remove BINARY_WEIGHTS option.

Revert "Cleanup: Use new utils provided by the asset system to get temp asset IDs"

This reverts commit b0395ba7186c1b0e1aede546b9ce2cfa41f5ffe7.

Merge remote-tracking branch 'origin/master' into asset-browser-poselib

Merge branch 'master' into cycles_procedural_api

Revert "Action: flip action data using pose contents"

This reverts commit d219b09a4802fff37189442de55720da6a03ea78. It was
accidentally committed to this branch, and is superseded by the actual
commits mentioned in D10781#274991

Fix library linking for editors/asset

Add missing libraries to fix a linker error.

Cycles: Support CUDA Graphics Interoperability

Allows to update GPUDisplay using CUDA without need to copy pixels
from GPU to CPU and back to GPU.

Pretty much refactoring the old code to fit into the new GPUDisplay
and PathTraceWork.

Rendering on CUDA Titan V which is the display card here is about 10%
faster vieweport rendering of simple scene compared to the round trip.

The compute device RTC6000 is 17% slower that the round trip.
Would not consider this a stopper for this change as the similar timing
difference can be observed in the old DisplayBuffer style of drawing.

Cycles: Use better check for CUDA graphics interoperability

The idea is to disable graphics interoperability if the compute device
is not part of the OpenGL context.

Test setup:
- Linux Debian Testing
- RTX 6000 used as non-display compute device
- NVidia driver 460.56

The render time of very simple scene in viewport is about 17% faster
than with an interop.

Cycles: Remove old pixels drawing and film conversion

The conversion to byte buffer is now a dead code. Would need to have
a decision to remove conversion to byte buffer, or to bring it back.

Cycles: Add comment about allocation size of PBO

Cycles: Use const qualifier in GPUDisplay reset

Only send all vcol layers to gpu (for pbvh drawing) in a material
draw mode.

* Sculpt color layers are now properly handle by pbvh bmesh draw code.
Before only the active layer was uploaded to the GPU, now all of them
(except the autogenerated original color layer) are.

Code cleanup
