Issue was that the `on_activate()` callback of tree-items were
continuously called, because the active-state was queried before we
fully reconstructed the tree and its state from the previous redraw.
Such issues could happen in more places, so I've refactored the API a
bit to reflect the requirements for state queries, and include some
sanity checks.
The actual fix for the issue is to delay the state change until the tree
is fully reconstructed, by letting the tree-items pass a callback to
check if they should be active.
The `ui::BasicTreeViewItem` took a function-like object to execute on
item activation via the constructor. This was mainly intended to be used
with lambdas. However, it's confusing to just have this lambda there,
with no indication of what it's for (activation).
Instead, assign the function-like object via an explicit `on_activate()`
function.
This adds an offscreen View3D window area for the VR view in order to
execute XR events/operators in the proper context. The area is created
as runtime data before XR events are dispatched and set as the active
area during XR event handling.
Since the area is runtime-only, it will not be saved in files and since
the area is offscreen, it will not interfere with regular window areas.
The area is removed with the rest of the XR runtime data on exit, file
read, or when stopping the VR session.
Note: This also adds internal types (EVT_DATA_XR, EVT_XR_ACTION) and
structs (wmXrActionData) for XR events.

Makes sure that the active item of a tree never has collapsed parent
items, which can be confusing if it happens. E.g. for the asset catalogs
UI, the active catalog decides which assets are visible. Having it
hidden while being the main factor deciding which assets are visible is
quite confusing.
I think it makes sense to have this at the UI Tree-View level, rather
than doing it manually in the asset catalog code for example. Seems like
something you'd commonly want. We can make it optional in the API if
needed.
Renamed the `set_active()` function to make clear that it is more than a
mere setter.
Adds an easy way to add drop support for tree-view rows.
Most of the work is handled by the tree-view UI code. The tree items can
simply override a few functions (`can_drop()`, `on_drop()`,
`drop_tooltip()`) to implement their custom drop behavior.
While dragging over a tree-view item that can be dropped into/onto, the
item can show a custom and dynamic tooltip explaining what's gonna
happen on drop.
This isn't used yet, but will soon be for asset catalogs.

Passing multiple UDIM arguments into the packing function
is awkward especially since the caller may not be using UDIM.
Use an argument to store UDIM packing parameters which can be NULL,
which operates without any UDIM support.
Add a function that extracts these parameters out of the image space
allowing for multiple functions to take UDIM parameters in the future.
The Asset Browser now displays a tree with asset catalogs in the left
sidebar.
This replaces the asset categories. It uses the new UI tree-view API
(https://wiki.blender.org/wiki/Source/Interface/Views#Tree-View).
Buttons are displayed for adding and removing of catalogs. Parent items
can be collapsed, but the collapsed/uncollapsed state is not stored in
files yet.
Note that edits to catalogs (e.g. new or removed catalogs) are only
written to the asset library's catalog definition files when saving a
.blend.
In the "Current File" asset library, we try to show asset catalogs from
a parent asset library, or if that fails, from the directory the file is
stored in. See adaf4f56e1.
There are plenty of TODOs and smaller glitches to be fixed still. Plus a
UI polishing pass should be done.
Important missing UI features:
* Dragging assets into catalogs (WIP, close to being ready).
* Renaming catalogs
* Proper handling of catalogs in the "Current File" asset library
(currently not working well).
The "Current File" asset library is especially limited still. Since this
is the only place where you can assign assets to a catalog, this makes
the catalogs very cumbersome in general. To assign an asset to a
catalog, one has to manually copy the Catalog ID (a random hash like
number) to the asset metadata through a temporary UI in the Asset
Browser Sidebar. These limitations should be addressed over the next few
days, they are high priority.

Own mistake when making NLA overridable, instead of assuming things
about the ID owner of the animation data being processed, properly
return and use the one found by `ED_actedit_animdata_from_context`.
Currently the Drivers Editor shows this (the blue thing can be dragged
to change frame):
{F10647661}
But the Drivers Editors X axis is the output of the driver [which can be
further tweaked by the curve] not time(frame).
So it seems better to not mix them here, it is just confusing to have
two different units on one axis.
Especially since what we really want to look at in X (the drivers output
value) can be in a totally unrelated range compared to frames, so e.g.
we might be interested in a drivers range from 0.0 to 1.0 and a
framerange of 100 to 200, so putting this on one axis just does not make
sense. Better to use a separate timeline for this.
Note 2.79 also did not do this.

This follows three main targets:
* Make creation of new tree UIs easy.
* Groundwork to generalize tree UIs (so e.g. Outliner, animation
channels, asset catalogs and spreadsheet data-sets don't have to
re-implement basic tree UI code) or even other data-view UIs.
* Better separate data and UI state. E.g. with this, tree-item selection
or the open/collapsed state can be stored on the UI level, rather than
in data. (Asset Catalogs need this, storing UI state info in them is
not an option.)
In addition, the design should be well testable and could even be
exposed to Python.
Note that things will likely change in master still. E.g. the actually
resulting UI isn't very nice visually yet.

Creating some primitives allows for a scale value (via python) that will
scale the object accordingly. For objects with a radius parameter
(like cylinders, spheres, etc.) passing a scale different to (1,1,1)
would result in unexpected behavior.
For example:
`>>> bpy.ops.mesh.primitive_uv_sphere_add(radius=2, scale=(1,1,2))`
We would expect this to create a sphere with a radius of 2
(dimensions 4,4,4) and then be scaled *2 along the z-axis
(dimensions 4,4,8). But this would previously create a scaled sphere
with dimensions (2,2,4).
The scale was simply divided by two. Maybe because the "radius"
parameter for creating the primitives was confusingly named "diameter"
(but used as the radius).
The fix adds a scale parameter to `ED_object_new_primitive_matrix`
and also renames the wrongly named "diameter" parameters to "radius".

last_accessed_column is reset when a new fcurve/mask/... is added to the keylist.

- Restore the initial view rect on edge pan cancel:
The initial view rect is now stored in the edge pan operator data.
When an operator with edge panning is cancelled it can now call the
`UI_view2d_edge_pan_cancel` function to restore the original View2D
rect.
- Less delay in node editor scrolling:
Delay is useful when scrolling through long lists, such as in the
outliner, but makes node scrolling feel sluggish and unresponsive.
The lower scroll speed here makes a faster response the better option.
- Zoom influence feature:
Somewhat slower scrolling in UI-space when zoomed out. With the 0.5
zoom influence factor nodes behave as if zoom factor is halved,
otherwise it gets too fast when zoomed out. Previously scrolling would
always be constant-speed in UI space, now it's half-way between UI
space and node (view) space.
This change reduces the GPU context switches when drawing keyframes.

the intention. That should also remind devs to decide if the operator
should apply for both file & asset browsing when copy & pasting operator

Before this, all asset view templates showing the same asset library
would show the same assets, even if they should show different ID types.
That was a major limitation since the design did forsee that this
template can be put anywhere in the UI to display various sub-sets of
assets.
Initially I did the ID type filtering close to the asset-list reading,
because I wanted to optimize reading so that we would only actually read
asset information from disk of the ID type to be shown. But this will be
quite complex and I'm not sure if I'll get to work on this anytime soon.
So this commit moves the filtering to the template display level solving
this limitation.
Note: This also adds the code to filter by tags, together with the ID
type. But it's not actually used anywhere yet.
