GPencil: Fix compile errors

Fix missing update enabling active pixels overlay in Cycles-X

Merge branch 'master' into cycles-x

fix socket recreation

Merge branch 'master' into temp-gpencil-bezier-stroke-type

Cleanup: remove comments on asserts in skin modifier, now that issue is fixed.

Merge branch 'master' into override-recursive-resync

LibOverride: Add heuristic protection against infinite loop due to libraries inter-dependencies.

This is not supposed to happen, but better be safe than sorry, and
assume it is beyond unlikely that someone would use chains of over 10k
linked libraries.

Refactor: Rename pass accessor in viewport parameters

No need to state that it is a viewport display pass, since the method
is within viewport parameters it is implied that parameters do belong
to the viewport.

Brings this code closer to the Cycles-X branch.

Refactor: Remove friend class from Cycles viewport parameters

Such pattern should only be used when it is really needed. Otherwise
just stick to a more regular design, without worrying who is the user
of the class. Otherwise it will be annoying to subclass or unit test.

Cleanup: const qualifier of return type

Cleanup: Use logical OR in Cycles background shader

Refactor: Naming in Cycles viewport methods

Makes it more explicit they operate on shading/light.

Gives room to move more viewport related settings into this class and
cover with specific or generic modification checks.

Cleanup: Redundnat member init in Cycles viewport parameters

Refactor: Move display pass to Cycles viewport parameters

Allows to centralize storage and modification checks in a single place,
avoiding duplication in the synchronization code.

Ideally we would somehow be able to more granularly modify Cycles side
objects. Leaving this for a future decision, because it might be better
to implement it as a graph on the sync side.

Cleanup: Unused include in Cycles
