Fix T70740: Clicking on proxy bone makes original one jump to initial location

Caused by what appears to be a missing flush from evaluated bone back to
original, which then makes it so copy-on-write operation happening after
click (to synchronize selection flags) pushes original bone to its initial
position.

Node shader wrapper: use 'Non-Color' profile for BW textures inputs.

All the single-value texture inputs of Principled BSDF node should use
non-color colorspace profile, not sRGB one (issue raised in
https://blender.stackexchange.com/questions/155617, thanks).

That also revealed another issue - since those color space settings are
stored at the image level itself, not the node one, we need to
duplicate those image data-blocks when we use same picture for e.g. base
color (sRGB) and specular (non-color) inputs...

For now using a basic mechanism for that, might generate several extra,
uneeded copies of the image ID, but that?s better than breaking custom
settings and such.

Note that while this will modify the behavior of the impporters using
that node wrapper, no change should be needed in IO add-ons themselves.

Fix T69182: Auto-Smooth does not work on Alembic meshes without normals

The auto-smoothing flag can now be used by artists when the Alembic file
does not contain custom loop normals.

- Auto-smoothing disabled: mesh is flat-shaded.
- Auto-smoothing enabled: works as usual; set angle to 180� to ensure
a 100% smoothed mesh.

Fix T70739: Make Library Override doesn't re-target Armature constraints.

Missing one step (collection prop itself) in RNA hierarchy of properties
leading to those armature object pointers...

Cleanup: spelling

Also remove historic bftgl reference.

GPencil: Fix unreported performance issue with relative onion mode

When the relative mode was used, the calculation of the total number of vertices was not done and it was using the total number of vertices in the datablock. This worked for small files, but with complex files the time to allocate all the data was too long and the performance was very bad.

Now, for relative mode the real number of vertex is calculated.

Also fixed the same problem when onion and multiedit is enabled.
