Driver: trailing zeros from expression

3D View: 3D Cursor was not restoring GL state

Caused camera frame to be double width.

UI: hide decorators in panels w/o animated buttons

Edit Mesh: tweak active face edge width

This rewinds a change from own commit e3d88b021c07d
The only took edge overlay into account (crease, seam.. etc)
Currently active-face also uses this width.

While the difference is subtle,
this makes the active-face stand out more clearly.

UI: correct decorator buttons 'enabled' flag

UI: decorator color button assert

Also set 'all' argument based on the RNA-index
(even though it worked, better set to correct value).

Cleanup: codestyle

Merge branch 'master' into blender2.8

CMake: add missing headers

GLRefactor: Remove all GL types from gawains public headers.

In preparation for possible alternative back-ends, the dependency on glew.h needs to be confined to as few libraries as possible. This patch removes all gl types from the public gawain headers.

It'll need some more refactoring later on, but for now this will suffice.
