Also use Vector to store menu search items instead of a linked
list. And extend the change into the autocomplete API slightly.
The main benefit is to avoid measuring the length of strings over
and over, but the code also gets simpler.
This patch adds support for drag and dropping colors (from color buttons) into
the Compositing, Shading and Geometry node trees.
Additional support was added for dragging and dropping colors with an Alpha
component (which was previously ignored), both in the context of the Node Editor
and for Color Buttons in general. This handles cases like drag and dropping a
color from an RGB to an RGBA button, which recreates the color with a default
Alpha value of 1.0.

Instead of requiring an image buffer to draw a bigger preview image
while dragging, allow passing an icon ID and draw that as preview. This
is also how we draw previews elsewhere. Use this for attaching the asset
previews to draggable buttons.
A small user visible change is that previews from the asset browser will
always draw at the default size (multiplied by the interface scale)
while dragging. Previously it used the same size as the asset browser
preview size, which I don't think was useful really. With small sizes
the preview while dragging got unnecessarily small too, with big sizes
it got in the way.
Needed for #131871.
A separate function is declared/defined `uiLayoutPanelPropWithBoolHeader`,
it will add a boolean property to the panel.header.
Clear decorate and separator flag, otherwise they will offset the panel
header horizontally and also adds animate decorator on the right side.

Papercut reported in #132293.
Allow explicitly disabling this behavior for a button, and do so for the
big preview asset shelf popup button. It gets more in the way than it's
useful in this case.
Similar to 2fbf206491, but for integers (not strings). Essentially this
allows passing named integer values through UI abstractions in a clean
way.
I used 64 bit integers here, since space isn't an issue here, and it
fits common integer types (so we don't have to add APIs for multiple
integer types).
Planned to be used to fix#111463 (following commit).
- Gives O(1) access to string length in more cases
- Convenient string manipulation functions
- Clarify difference between "no string" and "empty string"
- Avoid the need for raw pointers in the API
- Shows which API string arguments are optional

Adds support for saving some view state persistently and uses this to keep the
height of a tree-view, even as the region containing it is hidden, or the file
re-loaded.
Fixes#129058.
Basically the design is to have state stored in the region, so it can be saved
to files. Views types (tree-view, grid-view, etc) can decide themselves if they
have state to be preserved, and what state that is. If a view wants to preserve
state, it's stored in a list inside the region, identified by the view's idname.
Limitation is that multiple instances of the same view would share these bits of
state, in practice I don't think that's ever an issue.
More state can be added to be preserved as needed. Since different kinds of
views may require different state, I was thinking we could add ID properties to
`uiViewState` even, making it much more dynamic.

The preview template (`UILayout.template_preview()`) to display previews
for materials, textures or similar would only work correctly in the
Properties editor. This had explicit logic to trigger rerendering on
changes. When displaying such previews elsewhere (e.g. in the 3D View
sidebar), the only way to have changes reflected would be by resizing
the preview.
This fix makes sure such previews are tagged as dirty and refreshed on
changes to the underlying ID. We do this the same way as tagging the ID
previews as dirty, through a function called by the dependency graph for
such updates.

Generally increases padding of preview widgets a bit (while keeping the
preview size the same), and increases the size of the highlight surface
a bit. The default grease pencil brushes from the essentials asset
library use an opaque background, so the highlight was barely visible
before. It was difficult to identify the active brush from that. Now
it's a lot easier to identify visually.

This commit adds low-level logic in BKE to support three behaviors in
case of name conflict when renaming an ID:
1. Always tweak new name of the renamed ID (never modify the other ID
name).
2. Always set requested name in renamed ID, modifying as needed the
other ID name.
3. Only modify the other ID name if it shares the same root name with the
current renamed ID's name.
It also adds quite some changes to IDTemplate, Outliner code, and
RNA-defined UILayout code, and the lower-level UI button API, to allow
for the new behavior defined in the design (i.e. option three from above list).
When renaming from the UI either 'fails' (falls back to adjusted name) or forces
renaming another ID, an INFO report is displayed.
This commit also fixes several issues in existing code, especially
regarding undo handling in rename operations (which could lead to saving
the wrong name in undo step, and/or over-generating undo steps).
API wise, the bahavior when directly assigning a name to the `ID.name`
property remains unchanged (option one from the list above). But a new
API call `ID.rename` has been added, which offers all three behaviors.
Unittests were added to cover the new implemented behaviors (both at
BKE level, and the RNA/Py API).
This commit implements #119139 design.

The function would return two very different layouts in different code
paths, making it not clear to the caller what to expect. For one code
path the return value was rather useless, and in fact unused, so I was
able to just remove this. Also clarified behavior and return values in
the function API comment.
Since 5bcb0c9935, `uiLayout.template_ID()` already supports passing a label, in
which case the `uiLayout.use_property_split` would be respected. This makes the
template fit nicely with the surrounding layout, where buttons might have a
label split on the left, and a decorator button on the right.
This change brings the same to `uiLayout.template_search()`, plus makes it
respect `uiLayout.use_property_decorate`

For an NLA strip to use a slotted Action, it needs to specify which slot
to use in that action. This is now handled by two new properties on the
strip in DNA & RNA: `action_slot_handle` and `action_slot_name`.
These serve the same purpose as their counterparts on the `AnimData`
struct.
Note that this commit does NOT add NLA evaluation support for slotted
Actions. It merely allows assigning them. Evaluation, tweak mode
support, etc. will be implemented in future commits.

This removes the legacy Grease Pencil modifiers from the code.
These should have already been inaccessible from the UI and hidden from
the user. The modifiers have been reimplemented for the new GPv3
data structure.
On top of the modifier code, some other related things have been
removed as well:
* Operators related to the legacy modifiers.
* Keymaps for the legacy modifier operators.
* Some bits of code that used modifier functions.
Some code has to be kept, because it is still used:
* The core line art code, which is used by the new line art modifier. It's
moved to `modifiers/lineart`.
* The DNA structs for the legacy modifiers. They are still needed for
conversion.
* A few kernel functions for the modifiers are kept (also for conversion).

Match function and declaration names, picking names based on
consistency with related code & clarity.
Also changes for old conventions, missed in previous cleanups:
- name -> filepath
- tname -> newname
- maxlen -> maxncpy
Mostly to allow leak-free early exiting from functions generating the
tooltip data, otherwise cleanups have to be duplicated. But using smart
pointers is good practice in general. Also use references instead of
pointers, to indicate that null is not an expected value.
This gives users the ability to control the size of tooltip text
separately from other text styles. This is an accessibility issue
in that users with low vision can choose to make these larger than
the working text.

This PR removes the "Widget Label" text style, found in Preferences /
Themes / Text Style. This results in both labels and the text found in
input boxes sharing settings. This results in a slight loss of
customization but it isn't that useful to have these things separate
and results in code complication and errors.

Shortcut and quick favorite operators wouldn't show up in the regular asset
shelf. In the popup the shortcut operators would but they crashed with use
after frees.
Basic issue is that activating view-items by applying the button didn't work
well. That messes with button storage, but also the operator data (like
`uiBut.optype`) is unset after applying, in this case before the context menu
was built.
Instead, activate the view-item directly, and call the activate operator in its
`on_activate()` callback. The button shouldn't call this operator again, so
added a way to attach operators to buttons without calling them.
Seems generally useful to be able to attach an operator to buttons for
tooltips, "Assign Shortcut" and the like, without it being called on button
apply.

Turns the asset shelf into a popover which reduces some of the special
handling. An operator `WM_OT_call_asset_shelf_popover()` (similar to
`WM_OT_call_panel()`) is added to be able to call the popover from shortcuts.
Exactly this was an important aspect for the brush assets project, to allow
quick searching for brushes from the popup.
A custom shortcut can be added to asset shelf popovers using "Assign Shortcut"
in the context menu of buttons invoking it.
The popover is spawned with the mouse hovering the first asset and the search
button active using "semi modal" handling. That means while the popover is
open, any text input is captured by the search button, while the rest of the
popover stays interactive. So for example navigating through asset catalogs is
possible, a single click activates an asset and closes the popover.
Reviewed as part of the asset shelf project, see:

- https://projects.blender.org/blender/blender/pulls/106303
Adds support for text buttons that capture text input, while the rest of the
UI stays interactive. This is useful for example for filter buttons in popups
that are used for searching. Current search popups are an ad-hoc implementation
that doesn't use the normal widget system (and thus are quite limited).
For the brush assets project this is important to allow quickly popping up the
brush asset shelf popup, immediately typing to search a brush, and activating
a brush with a single click (rather than having to confirm text input first).
All UI elements stay interactive with hover feedback, changing asset library
and catalogs is possible, tooltips and context menus can be opened, and any
text input is still sent to the search button.
Normal search popups already keep their search results interactive like this
during text input, but are too limited because they don't use our widget
system. For example custom layouts are not possible with them. With this
feature implemented, we could consider rewriting them to use the widget
system, removing the ad-hoc implementation.

This change allows to pass optional freeing and copy callbacks to
functions setting the `func_argN` member of the `uiBut` and `uiBlock`
structs. These callbacks are used to free or duplicate the data stored
in these void pointers.
Defaults are set respectively to `MEM_freeN` and `MEM_dupallocN`, to
match previous hard-coded behavior.
Utils template functions are added to easily generate callbacks to
types that are managed with the `MEM_new`/`MEM_delete` C++-style
allocation, as long as they provide a copy constructor.
Note that this change should be considered as a temporary, transitional
solution. A more robust and future-proof solution is to move towards
more usage of `std::function` for these callbacks, which can then own
and manage their custom data themselves.
This makes it possible for popups to have their confirm & cancel buttons
defined in the operator's draw callback.
When used with popups created by: `WindowManager::invoke_props_dialog()`
to override the default confirm/cancel buttons.
In the case of `WindowManager::popover(..)` & `bpy.ops.wm.call_panel()`
this can be used to add confirm/cancel buttons.
Details:
- When the confirm or cancel text argument is a blank string the button
isn't shown, making it possible to only show a single button.
- The template is similar to UILayout::operator in that it returns the
operator properties for the confirm action.
- MS-Windows alternate ordering of Confirm/Cancel is followed.
Needed to resolve#124098.

Only when the user changes the UI font to one that does not have a
variable weight axis, update the text style weights to match the font's
design weight. So if changing to an old-school font that has a fixed
weight, for example bold, also update UI Text Style weights to match
so everything looks as designed and expected.

In particular, this makes the asset shelf popup search highlight the
first asset when changing the search filter using text input. Pressing
Enter will activate this asset then. The feature is implemented
generally for grid and tree views, but only the asset shelf implements
filtering so far. Plus, it requires the
`UI_BUT2_FORCE_SEMI_MODAL_ACTIVE` behavior on the filter text button,
otherwise it captures all input. Only the popup version of the asset
shelf uses this currently. Moving the mouse makes the highlight jump
back to the brush under the cursor again. This is how search menus
behave too.
Part of the brush assets project, see blender/blender!123853. It's made
so it's possible to quickly spawn the brush asset shelf popup, input
text to search a brush and press Enter to activate it. Based on user
feedback this is an important workflow to support well.

Reference identifiers instead of "above" in code comments as these
tends to become outdated. Even when declarations are removed it's at
least clear that the reference no longer exists instead of referring to
whatever is currently above the declaration.
It's also straightforward to search history for a removed identifier.
Corrected 4 cases of references to things that were no longer above
the doc-strings. Noticed other references which look to be incorrect
but need further investigation.
