Revert "GPUViewport: Use GPUBatch for viewport drawing"

This reverts commit 862ec829422241878b3345661476d8551935aed2. It causes crashes
on some systems, see T75584.

Fix for T75595: File Browser and Windows Unicode Paths

Fix for incorrect conversion to utf16 in BLI_file_attributes().

Modifiers: Add Bone option for Texture Mask Object

This patch adds the option to use an armature bone in place of an object for texture mask coordinates.

This affects the 3 vertex weight modifiers, the displace modifier, the warp modifier, and the wave modifier.

With minor changes from Bastien Montagne (@mont29).

UI: Better support for linked data-blocks in search buttons

In RNA pointer search buttons (i.e. the ones with an eyedropper),
data-blocks were handled badly. It was not possible to select a linked
data-block that had the same name as a local one, which is especially
common with library overrides. Neither was there a hint to tell appart
linked data-blocks and which .blend file they come from.
These issues are addressed now, we show an "L" prefix and the .blend
file name in the search box (like in ID-templates).

Changes here are quite simple, since the heavy lifting was already done
through c20c203b8226.

Addresses T73156.

Fix T75489: Crash on deleting current workspace from the outliner

It should not be possible to delete the current workspace from the
outliner. Show an error message instead.

Fix T74800 Bevel modifier generates vertex group weight > 1.0.

Due to floating point approximations, the weights for interpolating
the mdeformvert layer could add up to a tiny bit more than 1.0.
This was not a problem in practice, but the mesh validation routine
used in regression tests was testing for this and therefore failing.
Just changed interpolation of mdeformverts to clamp max to 1.0f.

Fix T75378: Crash on clicking in the ghost icon of an appended proxy object

Fix T67232: Multiples targetless IKs in a chain gives weird behaviour (known as FakeIK for FK posing)

The issue was that the deps graph relation builder assumed that all
bones that had a IK constraint on them would be evaluated. However for
targetless IK bones, only the active bone would receive updates and the
others would be skipped (as those would be treated as if the IK
constraint was disabled).

I didn't see an easy way to solve this from the depsgraph side of
things.

Instead I came up with a solution that I feel is quite strait forward
and reflects what is actually supposed to happen under the hood.

Now all targetless IK constraints are treated as disabled and will not
be added to any relations in the depsgraph.

Instead, a temporary IK constraint will be created when the bone in
question is transformed. This is basically activating "Auto IK" for the
bone while transforming.

Fix T71546: VSE stereoscopic strips issues with mismatched dimensions

The issue is that the cachiing was adding the right view without the

Issue was introduced in 5260aaf3b1c8 (fix for T73921).

Fix T75141: Default template versioning error for grease pencil

The versioning was done only for template because the code was after a return and never was executed for default scene.

Fix T74815: Shapekeys animation is blocked after second append of the same object.

Logic to handle shepkeys datablocks in helper in 'make local' code that
checks which ID should be copied, and which can be directly made local,
was wrong.

Fix T74657: Grease Pencil Proportional Editing does not work for
'Individual Origins'

Note gpencil doesnt do anything fancy like meshes in
editmesh_islands_info_calc(), but it looks like there is actually no
harm in allowing proportional editing with individual origins & gpencil
editmode.

Pointclouds: fix point drawing

The radius component is only one float. This resulted in only a third of
intended points to draw and could lead to glitches.

Pointcloud drawing will still change a lot in the future, this is just
to be able to work on some simple tools.

Shading: add Roughness input to Noise and Wave texture nodes

Currently in fractal_noise functions, each subsequent octave doubles the
frequency and reduces the amplitude by half. This patch introduces Roughness
input to Noise and Wave nodes. This multiplier determines how quickly the
amplitudes of the subsequent octaves decrease.

Value of 0.5 will be the default, generating identical noise we had before.
Values above 0.5 will increase influence of each octave resulting in more
"rough" noise, most interesting pattern changes happen there. Values below
0.5 will result in more "smooth" noise.

Collections: preserve exclude flag of child collections when unexcluding

Excluding a collection also changes the exclude setting on all child collections
so that it is possible to selectively enable some children without the parent
being enabled.

This change makes it so that if you unexclude the parent, the exclude setting
of children are restored again instead of being permanently lost.
