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

GPencil: Hide handles in stroke mode

Note that this does not show the stroke selection for bezier strokes
yet. This would likely have to be implemented in a new shader.

Merge branch 'master' into temp-explicit-colors

Merge branch 'temp-explicit-colors' of git.blender.org:blender into temp-explicit-colors

Geometry Nodes Curves: Refactor curve data storage

Each piece of data is now stored separately, not bunched up in a
control point class. This should help improve performance and
it's more aligned with the attribute approach.

Removed unused variables, fixed bug where polygon
geometry was being read twice, added comments.

USD Import: declared const parameter.

USD Import: USDMeshReader constructor fix.

EEVE: Lights: Implement simple culling scheme.

This has the basis of clustered light culling but does not yet do
it. The lights are only culled by frustum.

Its the same as if there was only one Cell for the entire Viewport.

Fix crash with "Current File" library and "Reload Scripts"

When a (Python defined) UI-list type is unregistered, we have to make sure no
list still references that type. We do the same for other such UI types.
This didn't happen to be an issue before, since the list type was not accessed
until the list was drawn again (which re-assigns the type).
