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.
The design is documented here:

Various changes to reduce risk of out of bounds errors in utf8 seeking.
- Remove BLI_str_prev_char_utf8
This function could potentially scan past the beginning of a string.
Use BLI_str_find_prev_char_utf8 instead which takes a limiting
string start argument.
- Swap arguments for BLI_str_find_prev_char_utf8 so the stepping
argument is first and the limiting argument is last.
This matches BLI_str_find_next_char_utf8.
- Change behavior of these functions to return it the start or end
pointers instead of NULL, which complicated use of these functions
to calculate offsets.
Callers that need to check if the limits were reached can compare
the return value with the start/end pointers.
- Return 'const char *' from these functions
so they don't remove const from the input arguments.
This patch removes the "Kerning Style" option for UI widget font
drawing and uses only the current default of "Fitted", since the other
option of "Unfitted" is just the result of truncation errors.

This button type shows a preview image above centered text, similar to
the File Browser files in Thumbnail Display Mode or the default Asset
Browser display. In fact we may want to port these over to use the new
button type at some point.
Will be used by the asset view UI template that will be added in a
following commit. That is basically a mini version of the Asset Browser
that can be displayed elsewhere in the UI.
This patch horizontally centers the text inside the progress bar
widget. It is currently left-aligned and offset to the middle, which
doesn't center properly.

IME conversion candidate window was displayed at the mouse position, instead of
below the cursor or text selection.
Blender need to tell the input method program where the conversion candidate
window is during Japanese and Chinese input.
In macOS, the `firstRectforCharacterRange` is called when input by the input
method starts, and the position of the conversion candidate window is
specified. Therefore, it is necessary to set the position of the conversion
candidate window before input starts. This patch changes it so that the position
of the conversion candidate window is always set when the cursor is drawn.

This patch adds a left aligned sidebar to the spreadsheet editor. This
Sidebar can be used to navigate the geometry component types and
attribute domains. It also provides a quick overview of domain sizes.
It replaces the two dropdowns in the regions header.
Next step will be to add the domain cycling shortcut
using the CTRL + mouse wheel.

Widget drawing code already supported drawing right-aligned, grayed out
shortcut strings. This patch generalizes things a bit so this can also
be used to draw other hints in the same way. There have been a few
instances in the past where this would've been useful, D11046 being the
latest one.
Note that besides some manual regression testing, I didn't check if this
works yet, as there is no code actually using it (other than the
shortcuts). Can be checked as part of further development for D11046.
A possible further improvement would be providing a way to define how
clipping should be done. E.g. sometimes the right-aligned text should be
clipped first (because it's just a hint), in other cases it should be
left untouched (like current code explicitly does it for shortcuts).
Removes the `UI_BUT_HAS_SHORTCUT` flag, which isn't needed anymore.
This patch improves the positioning of the little mnemonic underlines
shown under some hotkey letters in menus, especially when using custom
fonts.

This patch introduces non linear sliders. That means, that the movement
of the mouse doesn't map linearly to the value of the slider.
The following changes have been made.
- Free logarithmic sliders with maximum range of (`0 <= x < inf`)
- Logarithmic sliders with correct value indication bar.
- Free cubic sliders with maximum range of (`-inf < x < inf`)
- Cubic sliders with correct value indication bar.
Cubic mapping has been added as well, because it's used for brush sizes
in other applications (Krita for e.g.).
To make a slider have a different scale type use following line in RNA:
`RNA_def_property_ui_scale_type(prop, PROP_SCALE_LOGARITHMIC);`
or:
`RNA_def_property_ui_scale_type(prop, PROP_SCALE_CUBIC);`
Test the precision, step size and soft-min if you change the scale type
of a property as it will feel very different and may need tweaking.

This patch fixes the remaining issues described in T87749. The jitter
was caused by inconsistent rounding when using the floats icon_size
and icon_padding to offset the bound for the text drawing. Using
`round_fl_to_int` leads to consistent results and fixes the jitter
that remained in some buttons with icons, UI lists, and breadcrumbs.

This patch fixes jittering text when resizing regions of the UI as
described in T87749. The jitter was caused by the text padding
being stored as an integer which lead to inconsistent rounding.
Most notably this patch fixes the jitter in the new spreadsheet editor,
but not all occurrences of jitter described in T87749 (e.g. in UI lists)
are addressed.

The SB back-end optimizer for the mesa R600g driver corrupts the vertex
shader for widget drawing. This will not be fixed upstream because SB is
getting replaced as part of the new NIR path. This was thought to be an
issue with instancing and an attempted fix was submitted in D8374, but
it did not fix the issue.
This patch reimplements the array look-up part of the code using switch
case as a workaround and removes the old workaround implemented as part
of D8374.

Previously the padding size and the width saved for the icon were
constant regardless of the zoom level. This resulted in overlapping
icons and text, and ugly padding with more extreme zoom levels.
We can retrieve the size of the row from the `rect` argument.
Now the icon's rect are drawn wider than it should be, and with
overlapping, probably in order to compensate for the icon's offsets
inside the rect. The solution is to draw icon's rect of the correct
size and center the icon itself.
And make the hotspot exactly match the icon's rect. The last/right
button's hotspot also covers the extra padding on the right.

If there is enough space for both the item name and the library hint, display

not more than 60% and 40% of the available width are used repectively.
There are further improvements we could do, as noted in T84188, this just fixes
the regression for the release.
Part of T84188. There were multiple reports about this, see merged in and
mentioned reports in T84188 and T78012.
The cause for this was quite simple-- a misplaced bitwise operation
before passing a value to the function that grayed out buttons based on
their state, caused by refactoring in rB933bf62a611f before committing.
What makes the situation a little more confusing is that the theme colors
are overridden for list buttons in UI lists, necessitating a second
call to `ui_widget_color_disabled()`. Ideally that wouldn't be necessary.
This bug was caused by making it so that non-embossed modifier icon
buttons could become an operator button and retain their red highlight
for disabled modifiers. The icon button needs emboss turned off, but
in earlier versions of Blender, `UI_EMBOSS_NONE` would be overridden
by animation or red alert states.
Instead of abusing "NONE" to mean "none unless there is animation or
red alert", this commit adds a new emboss flag for that situation,
`UI_EMBOSS_NONE_OR_STATUS`, which uses no emboss unless there is an
animation state, or another status. There are only a few situations
where this is necessary, so the change isn't too big.

This commit adds functions to set and get the object's active
modifier, which is stored as a flag in the ModifierData struct,
similar to constraints. This will be used to set the context in
the node editor. There are no visible changes in this commit.
Similar to how the node editor context works for materials, this commit
makes the node group displayed in the node editor depend on the active
object and its active modifier. To keep the node group from changing,
just pin the node group in the header.
* Shortcuts performed while there is an active modifier will affect
only that modifier (the exception is the A to expand the modifiers).
* Clicking anywhere on the empty space in a modifier's panel will make it active.
These changes require some refactoring of object modifier code. First
is splitting up the modifier property invoke callback, which now needs
to be able to get the active modifier separately from the hovered
modifier for the different operators.
Second is a change to removing modifiers, where there is now a separate
function to remove a modifier from an object's list, in order to handle
changing the active.
Finally, the panel handler needs a small tweak so that this "click in panel"
event can be handled afterwards.
Adds smooth scrolling with the trackpad for popovers. Also fixes the position of the scroll arrows on high-DPI.
