Cleanup: some more valid G.main usages moved to G_MAIN.

Merge branch 'master' into blender2.8

Final cleanup of G.mains in render area.

Cleanup: names of WPaint gradient data structs.

instead!

Cleanup: remove DerivedMesh from WPaint Gradient tool code.

Name cleanup to follow.

Fix re-entrant calls in some cases of mesh_evaluated generation.

`mesh_get_eval_final` and friends could call `mesh_build_data`, which in
paint/sculpt mode would call `BKE_sculpt_update_mesh_elements` which
would call `mesh_get_eval_final`... ugly!

UI: tweak sequencer color space position, it's not related to display device.

UI: fix Ctrl-Wheel to change button values

Correction to previous commit.

There is no guarantee that given ob pointer is not also an evaluated one
here...

ModStack: Fix broken object_get_datamask helper.

Would compare evaluated ob pointer to original one...

Found while investigating some errors in incomming cleanup, but this was
probably generating lost of other issues in some cases...
