Cleanup: Add/use function to get area width/height from area vertices

This used to be rather cryptic and it was easy to forget the `+ 1` which in fact
is needed to get the correct width/height, see e626998a262ebe4f. This should
also fix some minor off-by-one errors.

Fix T54524: keyframe and driver colors not showing in shape key list.

This reverts commit 357b72e0a7d4a270bf1273102595446ccca16259 which caused
the issue, we need a better fix for that cosmetic issue from T50862. For
now displaying keyframes and drivers is the more important one.

Fix memory leak when using scroll-bars

Cleanup: Remove unused argument in recursive function

Cleanup: naming in MOD_utils.

Cleanup: Moar DM busting, mostly cleaning up MOD_utils.

Fix unnecessary empty space in shading popover.

Cycles: change AO node default to 16 samples and only local off.

Workbench: Spherical Harmonics tests

Added a compile directive in order to test SH4 in stead of SH2Win.
For now I disabled SH4, it is a bit more clear, but has a small
performance impact. Will check later for a better approach

Cleanup: remove another bunch of DM usages, includes etc.

Fix T55645: broken particle Use Count option for instancing objects.

There is now a manual refresh button on the panel to update the list
of objects in case it changes, and it also gets refreshed when changing
the collection or toggling the use count option.

This is a bit more manual but the previous code of refreshing the
list while evaluating the depsgraph was unreliable.

This also fixes it to take properly take into account visibility, and
to work with linked collections for which index writing was missing.

Keymap: re-enable object apply transform

Keymap: minimal default keymap

Use 2.7x keymap preset for full keymap.

Use define to allow further adjustments.

See T55666.

Refactor static override code to pass Main around.

Access to main database is actually rarely needed, but some custom
'apply' functions do need it (like Collections' overriding of objects or
children collections).

Cleanup: nuke G.main from BKE's particle_system.c

Cleanup: some moar DM kicking, in armature edit code.

Workbench: Transparent textures

Worknemch now supports transparent textures.
As the main engine is a deferred shading only a cutoff is supported
(draw or don't draw this pixel)

Workbench: remove runtime warnings

Added feature check when uploading material uniforms

Workbench: TAA optimalization

First frame of the TAA is just a regular copy of the previous buffer. so
we write directly to the final buffer and skip the taa shader. We do
init the history buffer via blit so it will be initialized for the other
iterations.
