Update to use GPU matrix

Merge branch '28' into custom-manipulators

Merge branch 'blender2.8' into custom-manipulators

Remove linkable vs appendable distinction in data-blocks.

This is complicating the code for a specific exception, which shall
hopefully be removed later even!

So better to go with a rather small, non-intrusive hack to prevent
linking Workspaces for now, link/append code in Blender is complicated
enough as it is.

Merge branch 'blender2.8' into workspaces

removed optional border velocities for obstacles

having just the velocities inside the obstacle seems sufficient for now (visually)

Transform orientations: Make code match blender2.8 as much as possible

Basically reverts e3c12bb139250b7573b and parts of cbaaeb8d9b6c95.
Decided to keep things close to blender2.8 here, D2687 can apply the
needed changes separately then.
It's okay if removing custom transform orientations behave a bit glitchy
with workspaces, all issues should get fixed with D2687.
