Fix driver for DeePoon HMD

Patch by @TheOnlyJoey, thx for fixing (and breaking!) this ;)

Merge branch 'master' into HMD_viewport

Make global areas draw-able

reordered cleanup before and after smoke step

transform_snap_object: More cleanup: Name and position of variables and functions

transform_snap_object: Style, cleanup and simplify `r_axis_closest` calcs

Add Top Bar space-type

Merge branch 'workspaces' into topbar

Merge branch 'blender2.8' into workspaces

Merge remote-tracking branch 'refs/remotes/origin/blender-v2.78c-release' into fracture_modifier

Little utility macros getter/setter compiler hints

Add WorkSpaceHook struct as bridge between workspace and window-manager

This way we can keep workspace and window-manager data separate and
further steps are made a bit easier.

Cleanup

Change name and organize position of functions

Simplification and comments

`dm->release(dm)` accidentally removed

I do not know if this call is really necessary, but in doubt I'll leave it as it is

Merge branch 'snap_system_clip_planes' of git@git.blender.org:blender.git into snap_system_clip_planes
