Fix T65834: Circle Select does not update select_id buffer after orbiting view3d.

This solution checks if `persp_mat` has changed. If positive, the selection buffer is redrawn.

Fix T63766: Multiresolution behavior when using crease edge

Switch to Gregory basis patches which are tangent continuous across their
boundaries.

Originally we've used BSpline basis patches to be more compatible with the
old subdivision code, but a lot of things changed anyway.

UI: Add decorators to Sequencer sidebar

These items you are very likely to want to animate.
Only adding for panels where it makes sense, so not Time or Source.

Revert "Particle system: Move runtime data to runtime field"

This reverts commit 36faf739a71624b6ca10cec7233779f9eeace0bd.

Somewhat annoying but this change had some unforeseen consequences,
which lead to an actual bug.

Since this change was not sufficient to get original report fixed
is easier to simply revert for now.

Fixes T65842: Hair disappears when clicking on particle system name

Fix: Alembic import segfault when importing mesh with null UVs

This fixes an issue introduced in 4337bc2e6303dbd5f295878f3e7490995a62713a.

Fix: wrong greying out in Sequencer sub-panels

UI: Further tweaks to Sequencer sidebar:

- Move strip name to the top (easier to see which strip you are adjusting, and more consistent with other areas)
- Move Mute next to this, since it affects everything, both audio and video, and completely disables the clip
- Mute now greys out all the Strip panels, since none of them apply if the strip is disabled
- Rename Info to Time, since now this panel only includes timecodes and related controls
- Move Lock to the Time header, since you are locking the time controls
- Move clip resolution to Source, since it's not related to time

Fix T62876: Camera Background Images

Migrate old legacy code to the draw mamager/object mode. The old legacy
version did not work with wireframe. By migrating the code
to modern draw manager code we have mode control on the drawing process.

Still background images do not work with OIT, the cause seems to be that the transparent pixels are treated as background pixels.
Also There are some artifacts when working with Holdouts and DoF, this
is because the draw engines do not pass the correct alpha values.

Fix T65745: Bone Selection X-Ray Drawing.

The Pose Bone Selection used normal matric multiplication, but that
mismatched the Depth buffer from all draw engines. They used the
optimized matrices from common_view_lib.

This change will use the optimized version, so the depth buffer matches
and the render artifacts would be correct.

Please note that bone selection is not using shcfg and therefore render clipping is still off.

Keymap: toggle all gizmos with Ctrl-`

Was only toggling transform gizmos, which is too specific
in cases where users might want to remove gizmos from the view.

This also follows the top-level button which is most prominent in the UI.

Cleanup: use trailing commas for multi-line arguments

Cleanup: don't use plural for forward/backward enum

Match existing enums.

Also use the term 'strip', instead of a 'clip'
(again, follow existing terminology, clip is used for movie-clip strips).
