This bug was introduced in D12190 because the list of types that support materials did not include GPencil and this caused all materials to be removed after they were created during conversion.
If the operator poll of a superimposed icon returned `false`, the
superimposed icon would just draw normally and fail silently. Instead it
will now be drawn grayed out, plus the tooltip of the icon can show the
usual "disabled hint" (a hint explaining why the button is disabled).
This seems to happen only in a few files, and not so trivial to
reproduce from scratch.
The crash is real though, and this fixes it.
It also fix a wrong comment style that was introduced in the same faulty
commit.
Bug introduced on ebe2374528.

Previously this was only happening when "Load UI" was enabled,
making it difficult for Python script authors to know when
re-registering subscribers was needed.
The breadcrumbs alone may not be enough to indicate that a user is
inside a nodegroup. The original dark green color was a bit overwhelming
but having a different background helps.
This is a follow up to 919e513fa8.
In previous Blender version the tile highlight was stored in the
full frame (un-cropped) space. This was changed with the Cycles X
development and now the tiles and render result are always measured
relative to the cropped region.

In a couple of places in the UI, we show superimposed icons on buttons
to execute an operation (called "Extra Icons" internally). Hovering them
would show the tooltip of the underlying button, which is misleading and
confusing.
There are cases where it's not obvious what an icon does, so a tooltip
would be quite useful here. It's likely we are going to use superimposed
icons in more places in the future, e.g. see D11890.
The extra icon basically acts as an override for the button in the
tooltip code.

Passing `options={'PERSISTENT'}` has no influence on this behaviour.
Disables undo for:
* The tree row collapsing - which doesn't make sense to undo, isn't
supported by the undo system, and just triggers the confirmation
prompt when closing the file.
* Renaming items - While this may make sense in some cases, users of the
tree-view API can explicitly do an undo push. For asset catalogs it's
not supported.
Moved function definitions around so that all members of a class are

Make the "xform" tool/gizmo available for strip transformations in the
sequencer preview window.
Because of the amount of hacks needed to make the gizmo work nicely with
multiple strips at the same time, it was decided to only show the
translate gizmo when multiple strips are selected.
This is because the transforms with multiple strips would appear buggy
because of our lack of shearing support in the transform system.
There is also currently no way to properly sync the gizmo drawing with
the transform when using multiple strips.

While drawing cleared this value (as part of temporary fix from 2009),
this was still being checked until recently.
Remove this value in versioning code.
Also clear unused text space flag.
- Drawing annotations used a deprecated value to detect
if drawing was supported.
- ED_space_sequencer_check_show_strip was checking the preview
image type (which doesn't impact strip display).

The current background color and parent nodetrees is too distracting and noisy.
It drastically affect the readability of the nested node-trees.
Other techniques (better bread crumbs) can be used instead to indicate
to users that they are inside a node group.

The background drawing was introduced in 4638e5f99a as part of the
Python Nodes branch merge. This made its debut in Blender 2.67
(30/May/2021).
At the time the color used for the background was a light gray. Over the
years the color changed to the current dark green, aggravating the
problem further.
Before that, the (expanded) nodegroup already had the partially
transparent background, mingling with the other nodes. The Python Nodes
branch brought this concept with its changes, and would always draw up
to two levels up in the background (the parent nodetree, and its parent
nodetree).
To read the original inspiration for all the changes introduced then:

Change the rules for determining where to save a new catalog definition
file (CDF).
Old situation (T91681): if a `blender_assets.cats.txt` file already
exists in the same directory as the blend file, write to that. If not,
see if the blend file is contained in an asset library, and write to its
top-level CDF.
The new situation swaps the rules: first see if the blend file is
contained in an asset library, and if so write to its top-level CDF. If
not, write a CDF next to the blend file.
As before, any pre-existing CDF is not just bluntly overwritten, but
merged with the in-memory catalogs.
sequencer_view_preview_poll returned true even when in the
"Sequence" view.
Now check the preview is visible, also check the region
is expected type so preview actions aren't possible for mixed
sequence/preview display.
The menu to select the active Asset Library is now in the left bar (so called
"Source List", although I'd prefer "Navigation-Bar").
This has some benefits:
* All Asset Library navigation is in the left sidebar now, giving nice grouping
and a top-to-bottom & left-to-right flow of the layout. The header is focused
on view set-up now.
* Catalogs are stored inside the asset library. Makes sense to have them right
under that.
* Less content in the header allows for less wide Asset Browsers without
extensive scrolling.
* This location gives more space to add options or operators for Asset
Libraries.
Main downside I see is that the side-bar needs to be opened to change
libraries, which takes quite some space. In practice there shouldn't be need to
do this often though.
This reworks how tree rows are constructed in the layout and how they
behave in return.
* To open or collapse a row, the triangle/chevron icon has to be clicked
now. The previous behavior of allowing to do it on the entire row, but
only if the item was active already, was just too unusual and felt
weird.
* Reduce margin between chevron icon and the row label.
* Indent child items without chevron some more, otherwise they feel like
a row on the same level as their parent, just without chevron.
* Fix renaming button taking entire row width. Respect indentation now.
* Fix double-clicking to rename toggling collapsed state on each click.
Some hacks/special-handling was needed so tree-rows always highlight
while the mouse is hovering them, even if the mouse is actually hovering
another button inside the row.
`SequencesMeta.new_movie()` API function caused meta strip to change
length. Similar issue has been fixed in transform code by checking
if `MetaStack` exists. `MetaStack` is not used when changing data in
python.
Provide `seqbase` to `SEQ_time_update_sequence()` so the function can
check if change happens inside of meta strip.
This patch also merges `seq_time_update_sequence_bounds()` into
`SEQ_time_update_sequence()`. This is because same issue applies for
both functions and it is confusing to have more time update
functions.re if this will lead anywhere.

Was just comparing this item's and the parent item's names. But if an item has
no parents, only its own name has to match for the check to return true. Make
sure that the number of parents also matches.
Now the icons to add or delete catalogs are only shown when mouse hovering a
catalog item in the tree. This is convenient for quick creation of catalogs,
and doesn't require activating a catalog to edit it first.
Determining if a tree item is hovered isn't trivial actually. The UI tree-view
code has to find the matching tree-row button in the previous layout to do so,
since the new layout isn't calculated yet.
The UI code to ensure consistent button state over redraws was just comparing
the name of the item, ignoring the parent names. So with multiple items of the
same name, there might have been glitches (didn't see any myself though).
There's a leftover to-do though, we don't check yet if the matched buttons are
actually from the same tree. Added TODO comment.
