Update to new clang-format code style

Add option to control de opacity of the sculpt mask

Merge 'master' into 'filebrowser_redesign'

Merge 'master' into 'filebrowser_redesign'

Merge 'master' into 'filebrowser_redesign'

Edit Mode: Make edit edges black by default

This is in order to have better contrast now that
the edges are half transparent if not
in edge selection.

DRW: Expose VBO garbage collection timings

This adds user side options to tweak the behavior
of the vbo garbage collection.

T63644: Editing while parented is not rotating correctly

This commit tries to fix the rotation problem when the parent is at layer level.

The problem was the object location was not used, so all object not in origin got weird transformations.

Fix T63669: Particle editing bypassing occlusion.

The problem occurs because status changes between BackBuffer and Offscreen.

Fix T63648: Missing update when changing particle force fields

Force fields requires relations update in the dependency graph.

Cleanup: Remove dead code

There is no more sorting happening, so the comment is out of date
by manu reasons. If something extra is needed there it would need
to be done differently anyway.

Edit Mode: Reduce Selected face alpha

This is to be less intrusive when doing UV mapping. They remain enough visible
in every select mode

Edit Mode: Change face mode edges display

This improve visibility in edit face select mode by using the face select color
instead of the edge select color (which is in default theme a bit more red). Also
makes the selected edges in this mode a bit more opaque (0.75 instead of 0.4).
Full opacity is still reserved for edge select mode.

DRW: Add batch garbage collection

This is only working for shading batches for the moment and only if some Custom data layer are not needed anymore.

The collection rate is hardcoded at 60 sec but could be exposed to the user.

This system can be extended and discard most unused batches in the future.

This commit is in prevision of removing BKE_MESH_BATCH_DIRTY_SHADING when changing shader parameters.

DRW: Make shaded batch validation more correct

This is in order to support garbage collection of unused Custom data layer uploaded to the GPU.

Actual Garbage Collection is not added by this commit.

Cleanup: Remove image preview code

Was commented out for literally 10 years.

Cleanup: Remove unneeded compositor update function

Similar to previous commit.

Compositing with animation on socket values and image sequences
still works fine.

Cleanup: Remove unneeded texture nodes update function

The function was calling update() on the time curve, but there
is no update callback on that node. So, effectively the function
was doing nothing.

Fix error in recently added STR_ELEM macro

Very bad oversight, using pointer comparison instead of strcmp
for all but the first item.

CMake: fix Cycles linking with OpenCL
