Hack: Let gizmos draw during playback to force VR gizmo redraws that way

We have to somehow force VR gizmos (i.e. the virtual camera) to
continuously redraw. Until there's a proper way to do that (e.g.
continuously redrawing certain gizmos without redrawing the rest of the
3D View), just allow playing animation to force these redraws.

Cycles: Fix viewport rendering when displaying as byte and not half float

Commit rB7e61e597253f3ca75f2fb86a57212ca750ffbbe8 broke viewport rendering when not displaying as halfs.
This fixes that by actually using the `scale` parameter that is passed into `film_map` and also de-duplicates code around it.
