The only_stroke parameter is not used

GPencil: Clean material list when convert a curve

Now the list of materials is cleanup and any duplicated material is removed.

GPencil: Move merge similar materials code to BKE

This is required in other places and need to be shared.

GPencil: Fix unreported problem in merge similar materials

When two similar colors were adjacent, the colors were not merged.

When the color was black, the original value was not initialized and get a NaN value with unexpected results.

Also cleanup code.

This allows to resample the stroke to avoid too dense geometry.

This parameter allows to scale the thickness.

The curve was using only the last point radius of the segment. Now, the value is interpolated between start and end points.

Fix T77424 Overlay: Editmode: Issue with multi edit and in-front option

This is a nice addition to the refactor. Now any combination of in-front
/ not in-front will work in non x-ray edit mode.

And do the clamp by vertex instead of triangle.

Fix T79738: Double Click does not opening folders in File Browser

If the File Browser was used in regular editor mode (e.g. not through an
operation like File > Open), the operator that usually opens files and
directories wouldn't execute. We need to keep two operators for
double-click in the keymap so selecting and opening works in all cases.

Caused by c606044157a3.

Merge branch 'blender-v2.90-release' into master

Fix (unreported) glitch when making liboverride of object from IDtemplate.

We need to ensure new override is instantiated in the scene...

Reported by @Severin, thanks.

Cleanup: Use const for context

UI: Category support for instanced panels

This adds support for panel categories to the instanced panel system
used for modifiers and others. The change is pulled from D7997 where
it is needed for FCurve modifiers, but it is unused now.

The change is simple and basically amounts to checking the panel
category where it was overlooked before.
