Interpolation tool for strokes ported from GPv2.
Adds a new operator that inserts a new frame with interpolated curves.
The source curves are taken from the previous/next keyframe.

This implements the _automerge_ feature which finds nearby end points
during stroke draw and merges the new curve with existing strokes.
New utility functions are added in `geometry` for slightly generalized
functionality. The `curves_merge_endpoints` takes an index map that
describes how to connect curves by index. It performs a topological sort
and reorders connected curves into contiguous ranges. This can be used
with an arbitrary number of connected curves. The tool feature itself
only uses a single curve, based on 2D end point positions.
Unit tests have been added for the curve merge utility function.

The (GPv2) fill tool has an "extension" mode to assist with filling
small gaps where strokes don't fully meet.
- Overlay: Draws various helpers during modal fill tool operation, using
the same functions as the render-to-image used for applying the fill
tool.
- Extension lines: Scrolling or page up/down extends the tips of strokes
and draws extra boundary lines to limit filling.
- Extension circles: Press S to toggle the mode. This draws circles
around stroke tips.
- Stroke overlay: This can be enabled in the brush settings
(_Advanced > Visual Aids_) to draw strokes in a simple color on top of
the viewport.
- Extension line collision: Tests for intersections of extension lines
with other lines and with strokes, and cuts them short. Enable in
brush settings (_Advanced > Strokes Collision_).
- Better defaults for extension increments: The values are in Blender
units, and quite arbitrary. Using lower values makes it feel more like
GPv2 in the 2D animation template.
- Draw functions in the `ed::greasepencil::image_render` namespace now
consistently expect coordinates in view space (avoids confusion and
works better for 2D elements).
- Some internal renaming and cleanup (many variable names come from GPv2
and were not very clear).

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.

Centralized method to obtain ScrArea icons. Areas can add an optional
space_icon_get callback to provide an icon that differs by subtype. If
not defined then ED_area_icon will return RNA UI icon, which is correct
in cases without area subtypes.

Our icon sources currently include two versions of the Blender logo,
the official one and one that is modified to align better to our
smallest pixel grid. But with our recent change to SVG icons, and
alignment tweaks to the official version this can be used in all
cases. This PR does so, removes BLENDER_LARGE, and also slightly
tweaks FILE_BACKUP and FILE_BLEND to use the official form.

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.

- https://projects.blender.org/blender/blender/pulls/106303
When opening the popup to select the asset catalogs to show as tabs in the
asset shelf, it's annoying that they would collapse back to the root level
every time. This would mean users have to manually uncollapse a bunch of
catalogs every time they call the popup. Since this is a popup, we don't need
to be too careful about saving space. And in practice these catalog trees are
usually rather small anyway. So simply uncollapse the first few levels of
catalogs.

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.

https://projects.blender.org/blender/blender/pulls/122871
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.

Rename 'Binding' to 'Slot'. The old term was causing all kind of
confusion, and 'slot' was considered to be a better term for the
intended functionality.
This commit breaks existing blend files that were using the new layered
Action for their animation. The animation data will be lost due to the
rename, as there is no versioning code or DNA renaming logic. At this
time the new system is still marked as experimental, so shouldn't be
used for anything serious anyway.

This moves the core of the cutter tool to
`ed::greasepencil::cutter::trim_curve_segments`.
This is in preperation for the draw tool which
also needs to be able to trim the stroke.
No functional changes expected.
In the Action mode of the Dope Sheet, show the Bindings, optionally
showing all Bindings in that Action. This also works when different
data-block types are animated from the same Action.
Bindings are selectable in the Action editor with box/range select.
Since there is no use for an 'active Binding' yet, this has not been
implemented, and as a result, clicking on a Binding does nothing.
Note on 'Binding' vs 'Slot': this code change was created before the
decision to change the name from 'Bindings' to 'Slots'. To avoid
confusion, and to keep this PR in sync with the code changes, it still
uses the term 'binding'. Renames of 'Binding' to 'Slot' in the code will
happen after this PR lands.

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.

This patch adds two theme entries for data before/after the current frame.
Those entries control what color to use when displaying
reference data from a different point in time (motion path, onion skins).
They are under the `3D Viewport` section of the theme in the user preferences.
## User Facing Changes
### Grease Pencil
When `Custom Colors` is disabled it will now use the theme instead of the layer default color.
Currently this setting is enabled by default. Disable it to get Blender to use the theme.
### Motion Path
If Custom Color is disabled, read from the Theme.
### Annotations
If onion skin is enabled, and custom onion skin colors is disabled, read from the theme.
**Grease Pencil**
* previously the color used for onion skinning (without custom colors) was `U.gpencil_new_layer_col`. This is used in other places as well so it cannot be removed with this PR
* By default, custom colors are enabled with Grease Pencil objects. I specifically did **not** change that with this PR. I will instead let the GP module handle that on their terms.
This PR has been discussed in the Grease Pencil module meeting
https://devtalk.blender.org/t/2024-05-21-grease-pencil-module-meeting/34755#meeting-notes-2

No user visible change expected.
There's no good way to identify items from their base class which is
annoying for development/debugging. I ended up adding a helper like this
a few times, so makes sense to just add this to the API.
On started Blender was scanning icons for PNG's to display in the theme menu
which hasn't been available since early 2.x days.
Also remove some other unused icon functions.

Use new SVG icons in place of current "Alert" icons, used on dialogs
and confirmations. No need for alert_icons.svg, alert_icons.png,
alert_icons_update.py. Also looks better as they are made at exact
requested size instead of 256x256 then scaled down to display.

Add definitions for the UI icons that we use in larger sizes, like in
the File Browser or in dialogs. The SVG source files for these are
already in the project, this just allows their use like ICON_FILE_LARGE
or ICON_WARNING_LARGE.

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.
Using ICON_NONE causes textures to be referenced even though nothing
is ultimately drawn. This adds an early exit for this value, and also
changes the type of it from ICON_TYPE_COLOR_TEXTURE (used to display
a full-color bitmap) to ICON_TYPE_MONO_TEXTURE (normal one-color type
now coming from SVG).
Pull Request: https://projects.blender.org/blender/blender/pulls/123609
Distribute our UI icons as separate SVG files in a folder in the
Blender installation. Rasterize each only when requested at the exact
size needed, and then saved in the text glyph cache for later uses.

Basically this tries to make the API to stop and kill jobs more explicit &
consistent, so intent is expressed clearly & behavior as expected.
- Remove use of the job start callback address as identifier for the job.
6887dea786 already removed this pattern from the jobs system internals, this
commit also removes it from the API.
- Make stop & kill API and implementation consistent. E.g. don't stop/kill jobs
by either owner **or** type/callback in one function, and by owner (if
provided) **and** type/callback in another. Causes some small behavior
changes, documented inline.
- Use the same job type and API for all preview render jobs (change by Brecht).
There doesn't seem to be a need for the separated types, in fact the
separation might have caused some issues earlier (and added code complexity).
- Add/improve function documentation.
This does actually have subtle behavior changes that are known, see PR, but
they were investigated carefully and seem like implementing wanted behavior.

The fill tool can take opacity into account ("Advanced" brush settings).
In that case any point with a total opacity lower than the threshold is
rendered as a transparent boundary.
This was still a hardcoded setting in the fill tool, now uses brush
settings.

Currently, when color-picking from the viewport, the code will read the final
displayed pixel color and then somewhat attempt to undo the display transform.
However, this has several limitations - for example, precision is limited to 8
bit, and it does not account for e.g. View Transform or exposure/gamma.
Since we have the pre-display-transform color in a GPU texture anyways, this
code therefore adds a View3D-specific eyedropper handler (similar to e.g.
the image space) that reads from the viewport texture.

This PR modifies the check for visibility when selected in the outliner.
With the change the visibility check only affects the selection state, not the active state.
The check has also been swapped with a function call to `ANIM_bone_is_visible_editbone`,
so now correctly works with collection visibility.
This PR also fixes the same issue for `Bone` and `bPoseChannel`
