Merge branch 'master' into experimental-build

Fix error checking edit mode button in VFX

Merge branch 'blender2.8' into greasepencil-object

New VFX pixelate modifier

fixes for centroid and volume calculation for non-manifolds, fix attempt for storage of merge info

Fix leak in Python BGE filter & image types

Added first triangulation to generate the fillets. Still needs ring order and assignment though.

Fix T46329: scene_update_{pre,post} doc needs clarification

The documentation for the bpy.app.handlers.scene_update_{pre,post}
handlers states that they're called "on updating the scenes data".
However, they're called even when the data hasn't changed. Of course
such handlers are useful, but the documentation should reflect the
current behaviour.

Fixed Alembic unit test

Commit b6d7cdd3cee9312156e20783248a3b12420b7a53 changed how the mesh data
is deformed, which wasn't taken into account yet in this unit test.

Instead of directly reading the mesh vertices (which aren't animated any
more), we convert the modified mesh to a new one, and inspect those
vertices instead.

Fix T52240: Alembic Not Transferring Materials Per Frame

When a mesh changes its number of vertices during the animation,
Blender rebuilds the DerivedMesh, after which the materials weren't
applied any more (causing the default to the first material slot).

Alembic: Renamed variable assigned_name ? assigned_mat

The variable is a pointer to a Material, not to a name/string.

Cycles: Fix for a division by zero that could happen with solid angle triangle light sampling

Fix T52401: "Export Keying Set" operator generated incorrect ID's for shapekeys

To be backported.

Fix OSX duplicate path in Python's sys.path

The '..' in the path caused simple comparisons to fail.

Fix T52255: New Depsgraph - Constraint and Drivers not working together when the driver references itself

Alembic import: report object name in face color index out of bounds error

Alembic import: fix crash when face color index is out of bounds.

This can happen with Alembic files exported from Maya. I'm unsure as to the
root cause, but at least this fixes the crash itself.

Thanks to @looch for reporting this with a test file. The test file has to
remain confidential, though, so it's on my workstation only.

Fix T51701: Alembic cache screws up mesh.

Use same trick as in DataTransfer modifier e.g. to avoid modifying
existing mesh's data.

Forgot to change magicnumber of OIIO built lib in previous commit...
