Blender Git Loki

Renamed create_rotation_matrix to create_swapped_rotation_matrix and more:

Also replaced the bool param "to_yup" with "AbcAxisSwapMode mode", so that
it's more explicit that axes are swapped.

Also added unittests for create_swapped_rotation_matrix.

CMake: Fixed order of bf_alembic in SETUP_BLENDER_SORTED_LIBS

bf_alembic depends on bf_bmesh, and should therefore be above it.

save and load obstacle velocities (for standalone mode)

Merge branch 'master' into soc-2016-pbvh-painting

added union in sculpt session for modes. Sculpt fields could use some tidying, but that might be outside the scope of this branch. Swapped out some free patterns with MEM_SAFE_FREE. Swapped a long out for an int, since there's no size difference.

Remove USE_IMM ifdefs

Finish of removal of GLU deps

Will commit full removal next

Fix workspace mode syncing

Toggling off a mode didn't correctly update the workspace.

fix ps->go = false;

fixed masking bug, & pbvh freeing bug. Still trying to figure out grids...

initial commit: call the `playanim_window_open` only once

immInit should only be called once per application.
However, immediate mode only works if a GHOST window is created.
But every time you drop a video in the anim player, `GHOST_DisposeWindow` is called and a new window is created next. Forcing destroy and init a new immediate mode context :

This patch changes the order of things. And call `GHOST_SetClientSize` intead `GHOST_CreateSystem`, `GHOST_CreateEventConsumer`, `GHOST_AddEventConsumer` and `playanim_window_open`.

FIXUP stupid rotation mode y=up bug

Alembic import: fixed crash on more complex model

There was a problem with parent-child relations not getting set up
correctly when an Alembic object was both the transform for a mesh object
and the parent of other mesh objects.

Alembic: comment typo/error fixes

install_deps: removed leftover compile_HDF5 command

It was a leftover from when Alembic with HDF5 was still officially
supported.

Some more cleanup, get rid of hack to protect against NULL RNA pointerprops.
