Fix T83856: Sculpt: anchored brushes with spherical falloff ignore topology automasking

Anchored brushes with spherical falloff start off with zero radius, thus
we have no pbvh nodes on the first brush step. This would prevent
initializing the automasking cache [which only happens on the first brush
step].

Fix sequencer transform test failing

This was casued by incorrect versioning keyframe conversion in
recent commit 571362642201.

Allow vertex tools to operate on weight groups when armature is in object mode

Since a few versions (even before 2.79) we have an option that allows to restrict the vertex tools to operate only on deform groups. This was originally implemented for working with vertex groups for skeletal animation. In that case it is fortunate to have weight tools operate only on deforming vertext groups (vgroups assigned to bones)

In previous versions of Blender (up to 2.79) we have been able to use this option in Mesh Edit mode regardless of the armature mode. The current implementation (since 2.80 as far as i know) enables this option only when the associated armature is in pose mode. this has a bad consequence:

It is not at all intuitive that you have to put the armature into Pose mode before you can make use of the option in mesh edit mode.
Besides this it is not even necessary in the case when the user wants to restrict the tool only to all pose bones. In that case the armature can safely be kept in Object mode. However, when the tool shall apply only to selected pose bones, then it actually makes sense to have the armature in pose mode (as it is implemented right now)

I do not know why this feature has been restricted as described above. It must have got lost somewhere on the way to Blender 2.90

This patch fixes the issue as it allows to select the "restrict to pose bones" option when the armature is in any mode. I see no downsides of this change, actually this is a fix for a feature that once worked and apparently got forgotten in newer releases.

VSE: Improve motion-picture workflow

This commit resolves problem introduced in e1665c3d3190 - it was
difficult to import media at their original resolution.
This is done by using original resolution as reference for scale.

All crop and strip transform values and their animation is converted
form old files.

To make both workflows easy to use, sequencer tool settings have been
created with preset for preffered scaling method. This setting is in
sequencer timeline header and add image or movie strip operator
properties.

Two new operators have been added:
`sequencer.strip_transform_fit` operator with 3 options: Scale To Fit,
Scale to Fill and Stretch To Fill.
Operator can fail if strip image or video is not loaded currently, this
case should be either sanitized or data loaded on demand.

`sequencer.strip_transform_clear` operator with 4 options:
Clear position, scale, rotation and all (previous 3 options combined).

Ghost/Linux: Avoid error print if special directory can't be determined

The function is supposed to fail gracefully if there is some error. That
includes not being able to find `xdg-user-dir`. So don't let the error
be printed to the console, it's misleading/annoying.
From what I can tell we'll detect that problem fine and return NULL
then.

Geometry Nodes: Add boolean attribute in utility function

This follows up rBc484b54453e607, adding the boolean custom property
data type in one more place that was missed.

Geometry Nodes: Boolean attribute type

This adds a boolean attribute and custom data type, to be used in the
point separate node. It also adds it as supported data types in the
random attribute and attribute fill nodes.

There are more clever ways of storing a boolean attribute that make
more sense in certain situations-- sets, bitfields, and others, this
commit keeps it simple, saving those changes for when there is a proper
use case for them. In any case, we will still probably always want the
idea of a boolean attribute.

* Bring in a new distribution method for the point scattering node

Patch Review: https://developer.blender.org/D9787

Note: This commit doesn't not handle doversion. Which means that users
need to manually update their files that were using the Point Distribute
node and reconnect inputs to the "Maximum Density" socket.

Sculpt: Multires Displacement Smear

This tool implements smearing for multires displacement over the limit
surface, similar to how smearing for colors and topology slide works.
When used the displacement values of the vertices "slide" over the
topology, creating the effect of smearing the surface detail.

As the brush just modifies displacement values instead of coordinates,
the total displacement of the affected area doesn't change. This means
that this smearing effect can be used multiple times over the same area
without generating any artifacts in the topology.

When the brush is used with the pinch or expand smear modes,
displacement differences are pushed into the same area, creating hard
surface effects without pinching the topology.

As any other brush that relies on the limit surface (like displacement
erasers), this will work better after using apply base.

Fix T83843: Crash in Asset Browser sidebar with geometry asset selected

No icon should be created if the preview doesn't exist.

Asset Browser: For assets without preview, show type icon in sidebar

Otherwise it would just show empty space where the icon is supposed to
be.
Unfortunately this icon is upscaled quite a bit and doesn't look too
great. Would be good to improve but not a high priority.

BLI: remove implicit casts between some span types

Casting pointers from one type to another does change the
value of the pointer in some cases. Therefore, casting a span
that contains pointers of one type to a span that contains
pointers of another type, is not generally safe. In practice, this
issue mainly comes up when dealing with classes that have a
vtable.

There are some special cases that are still allowed. For example,
adding const to the pointer does not change the address.
Also, casting to a void pointer is fine.

In cases where implicit conversion is disabled, but one is sure
that the cast is valid, an explicit call of `span.cast<NewType>()`
can be used.

Fix: Python warning in windows debug builds

When doing a debug build on windows, blender will
start with the following warning:

"Unable to find the python binary, the multiprocessing
module may not be functional!"

The root cause for this issue is: for a debug build
the python binary is called python_d.exe rather than
just python.exe

This change fixes BKE_appdir_program_python_search
to look for the _d suffix for debug builds on windows

LibOverride: Better handling of missing linked data during resync.

We do not generate overrides for missing data-blocks (aka placeholder
ones) anymore, and properly delete the remaining old overrides of those
during the resync process.

This should prevent constant 'missing data-blocks' messages when opening
blend files with overrides whose libraries have beed edited.

Fix T83801: UVEditor translation ignores "Pixel Coordinates" and aspect
ratio

Caused by rB4eda60c2d82d.

T83801 reported not moving in pixel space, but even without that toggle
above commit caused the translation to not take apsect ratio into
account properly [a translation of 1 on the x axis for example on an
image with non 1:1 aspect ration caused the UVs to not end up in the
same place on the next 'tile']

Above commit removed 'removeAspectRatio()' [the counterpart of
applyAspectRatio -- which does the pixel coord correction internally]
from 'applyTranslation()'.

This was also reported in T83352 [which was closed by rBf3b08af24c9f --
but that only solved the displax in header, not the actual
transformation]

Now bring back 'removeAspectRatio()'.
