Since rB329b4c3363e4 a texture preview is not rendered through the
preview.blend and a renderengine anymore [unlike materials etc.]
Alpha wasnt handled in that commit, take that into account now.
sidenote: not sure if we should be looking into drawing alpha with a
checkerboard in the background for texture previews (see texture
previews elsewhere)?
sidenote 2: might also be good to document where the "calculate" and
"invert" alpha options are still used? [looks a bit inconsistent:
compositor uses it, Image Editor as well as Render Engines dont?]

Checking T_PROP_EDIT_ALL returns true for _any_ of the options, so just
check for T_PROP_EDIT.
Note: this might expand to other similar checks (e.g. header text)

The was caused by 8b347fc2cd as the old BONESEL_NOSEL flag
handled the -1 case (used for none).
Instead of checking for -1, remove these elements from the array
as selection code makes decisions based on the number of hits detected.
Local datablocks (including overrides) need to have a unique name, which
can then differ from the reference linked one (especially when there are
several local overrides of a same linked data).
Issue is, ID name is a 'rna name property', and as such used as
reference when dealing with override of collections of IDs, so we cannot
have a changing name.
The solution implemented here should work and is simple, but it may have
some issues in corner cases (time will say), it is not really robust.
Alternative solution would be to store ID pointers as reference in
override operations, instead of there name. But that would potentially
add quiet a lot of overhead to foreach looping in `lib_query.c`.
This code is currently only used for the Glossy Toon BSDF, but it's a generic
building block that might be used for other things in the future.
To see why the current code does not give a uniform distribution, consider that
it chooses both angles uniformly, but the smaller the angle from the center of
the cone is, the smaller the differential solid angle is (similar to how
sampling disks by choosing radius and phi uniformly does not work).

Also, remove manually placed decorator for vertex groups in modifiers. This was
only needed because of this bug, and the layout was slightly misaligned.
This will fix situations where the modifier epansion was set elsewhere
besides the UI, like from the python console, solving the drawing part
of T77502.
Also adds update tags to the show_expanded property, which means
the properties window redraws when the property changes.
This operator performs an edit operation in the active face set defined
by the cursor position and updates the visibility. For now, it has a
Grow and Shrink operations, similar to Select More/Less in edit mode or
to the mask filter Grow/Shrink modes. More operations can be added in
the future.
In multires, this updates the visibility of an entire face from the base
mesh at once, which makes it very convenient to edit the visible area
without manipulating the face set directly.

This implements squash and stretch as a deform mode for the Pose Brush.
It is similar to scale, but it applies different scale values in different
axis. To achieve this, the pivot local space of the transform needs to
be aligned to the segment when using this deform mode to apply the scale
in the correct direction.

Previously the scale of the text was using object space, so when working
with scaled objects or small meshes the size of the text was wrong. Now
it calculates a scale in screen space, so the text size should be much
more predictable

E.g. simply on button hover changes, the tree would be needlessly rebuilt.
I wouldn't be surprised if this causes side-effects, for some state changes we
may still have to do a full rebuild.
This adds two data structures that wrap a node tree. However, they work
on different abstraction levels.
`NodeTreeRef` is an immutable structure that makes working with a node
tree in C++ much more efficient and convenient. It supports various
queries efficiently, that are not easily possible using just `bNodeTree`.
`DerivedNodeTree` builds on top of `NodeTreeRef`. It contains a flattened
view on the node tree, i.e. with node groups being inlined. Every inlined
node still knows its "call stack". It supports pretty much the same queries
as `NodeTreeRef`.
Both data structures come with a dot graph exporter for debugging purposes.

A regression caused by c57f65c088 as a fix of another issue.
Added an exception for camera solver as that is always pointing
to camera object.
Since this is a regression which happened in 2.83.0 this change is
a candidate to be ported to the 2.83.1.
Pointed by strict compiler warnings, but some of the reports were
actually a real bugs:
- Access uninitialized memory of td_mirror_iter.
Assuming that iterator is to point to the first element of the
data array.
- Lattice's recalc data was never called.
There is also a fix for redundant declaration of recalcData() and
missing declaration of recalcData_lattice().
This also renames `MutableArrayRef` to `MutableSpan`.
The name "Span" works better, because `std::span` will provide
similar functionality in C++20. Furthermore, a shorter, more
concise name for a common data structure is nice.
The main focus here was to improve the docs significantly. Furthermore,
I reimplemented `Set`, `Map` and `VectorSet`. They are now (usually)
faster, simpler and more customizable. I also rewrote `Stack` to make
it more efficient by avoiding unnecessary copies.
Thanks to everyone who helped with constructive feedback.

This change modifies the multi-device implementation to support memory distribution
across devices, to reduce the overall memory footprint of large scenes and allow scenes to
fit entirely into combined GPU memory that previously had to fall back to host memory.

This adds a new `CPPType` that encapsulates information about how to handle
instances of a specific data type. This is necessary for the function evaluation
system, which will be used to evaluate most of the particle node trees.
Furthermore, this adds an `IndexMask` class which offers a surprisingly useful
abstraction over an array containing unsigned integers. It makes two assumptions
about the underlying integer array:
* The integers are in ascending order.
* There are no duplicates.
`IndexMask` will be used to "select" certain particles that will be
processed in a data-oriented way. Sometimes, operations don't have to
be applied to all particles, but only some, those that are in the indexed by
the `IndexMask`. The two limitations imposed by an `IndexMask` allow for
better performance.

The current particle state is stored in a `CustomData` instance and
the cache is stored in `PointCache`.
The current state exists on the copy-on-write copies of the simulation,
while the cache only exists in the original data block.
This patch implements a temporary trivial particle simulation that does not
use the node system yet. It is used for testing and will be replaced soon.
`PointCache` still has some limitations that need to be overcome using
separate refactorings. For example, we need to be able to store the number
of particles in the point cache. Also we need to change which attributes
are stored for a particle system more dynamically than is currently possible afaik.
