Slightly better code to handle default 'interpolation' of bool flags.

Merge branch 'master' into mesh-transfer-data

Writer/Reader classes for the mesh cache modifier.

Dummy point cache instance in the mesh cache modifier, as a test bed for
mesh data export/import.

Fix for changed function signature in freestyle code.

Extra check for cache user info when running the generic point cache
export operator.

A couple of fixes for changed Blender functions and the new
EvaluationContext needed for evaluating the scene during baking.

Linux library linking is now in a cmake macro file.

Include Alembic build arguments in BUILD_INFO.txt.

Install Alembic in $INST path directly, use the subfolder created by
Alembic build files themselves.

Alembic support in the install_deps.sh script.

This is a rough-and-ready way of building and installing the Alembic
library and the necessary dependencies (excluding as much as possible
for now). The Alembic cmake files are very badly constructed and require
some annoying hacks atm. Eventually we might try to supply them with
patches or write our own build scripts for Alembic.

Deselecting GP strokes deselects them for all frames and all (editable) layers

Bugfix: Sequencer properties panel doesn't update when new Grease Pencil data is added

Bugfix: Sequencer Preview doesn't update when stroke selection changes

Merge branch 'master' into mesh-transfer-data

More fixes and refinements:

* Now edge projection starts to show some results (quite useful for things like edge seam transfer).
* Better handling of bitflags default 'interpolation' (binary-choose value representing the highest sum of weights).

passing inflow adaptive grids without disk files

More API reorganization

Merge branch 'master' into temp_custom_loop_normals

Add new mapping code for M2MMAP_MODE_EDGE_EDGEINTERP_VNORPROJ.

This is similar to M2MMAP_MODE_POLY_POLYINTERP_PNORPROJ, but for edges.
Also fixed a bunch of logical flaws in this poly one.

All this remains 100% theory currently, not tested at all yet.

Also some minor cleanup.
