For the man rationale behind this design, see 49f088e2d0. Further,
this removes users of uiBut.a1/uiBut.a2, which is a very ugly design
choice (hard to reason about).
Note that I had to do rather ugly, specific exceptions for the number
buttons in `ui_def_but_rna()`. But once all users of a1/a2 are removed,
this special handling shouldn't be needed anymore.
I also had to move a sanity check out of the button definition. It's now
moved into a new debug only sanity checking function executed when
finishing the layout definition (block end).
We do this in a couple of places, so it's worth having the logic wrapped
into a function.
Also, the only way to set the disabled hint for a button from outside of
`interface/` was through `UI_block_lock_set()`/`UI_block_lock_clear()`,
for which the usage isn't obvious when you just try to disable a single
button.
- Use WM_operatortype_description to get the operator description.
- Pass properties to WM_operatortype_name,
so the operator name callback is used.
- Add UI_but_operatortype_get_from_enum_menu function
to access the operator from enum menus.
- Change WM_operatortype_description to return NULL when there is no
description, use WM_operatortype_description_or_name
when either can be used.
Steps to reproduce were:
* Open Sequencer, add a sound strip
* In the sidebar, open the Adjust > Sound sub-panel
* Note the placement of the "Mono" item
The layout code would disable decorators if a property came from a
non-animatable data-block type. Doing so would mess up the alignment
where properties from different data-block types were be mixed.
This is not the case any more.
Note that when actually adding the decorator, a blank icon is inserted
to keep the alignment intact when the data-block type isn't animatable.
So the decorator is still not shown, but the alignment looks fine.
This may affect more cases. If so, and if that's an issue, the
decorators should be explicitly disabled.
I only skipped a few loops in the monstrous ui_handle_menu_event
function. Also, I only changed variable names where necessary to
prevent redeclarations.

The current on-size-fits-all `uiBut` creates quite a mess, where it's
hard to reason about which members are free for use, under which
conditions they are used and how.
`uiBut` also has members that aren't used at times, violating the "don't
pay for what you don't use" principle.
To address this, we want to move to typed buttons, where `uiBut` is just
a base struct and each type extends it as needed. That structures data
better and type specific data is only available if it's actually used by
a button type.
Two trade-offs:
* Many casts to the derived type have to be done.
* Sometimes we change the button type after it's created. So I had to
add logic to reallocate the button for use with the new, possibly
derived struct. Ideally that wouldn't be needed, but for now that's
what we have.

ad4928a171 disabled alignment for too many cases. Still try to avoid
aligning many items, to avoid thousands of redundant alignment
calculations. But now we're much more picky adding an sub-row with
alignment.
Use 'emboss' instead of 'draw_type' as enum, layout & functions use
the term emboss.
This issue was noted by @Poulpator in D8414, as `dt` is also an
abbreviation for delta-time.
There was a weird looking gap between the checkbox and the "Motion Tracking"
label. Plus, the label could not be clicked to change the value, unlike
usually.
Issue is that the row is actually a sub-panel header. The checkbox being drawn
with the draw_header() callback, and the label being added as separate item by
the popover panel code. This adds a hack so the checkbox can add the panel
label itself (the popup drawing skips adding the label then). That addresses
mentioned issues.
Key-map display was doing thousands of redundant alignment operations.
Set the spacing instead as align was only set to use zero spacing.
This would have prevented the crash reported by T78636.
This addresses warnings from Clang-Tidy's `readability-else-after-return`
rule in the `source/blender/editors/interface` module.
No functional changes.
The shortcuts act on the modifier with its panel under the mouse.
The following shortcuts are enabled by default:
- Remove modifier: X, Delete
- Apply modifier: Ctrl A
- Duplicate modifier: Shift D
More shortcuts can be added in the keymap.
Each panel can now store a custom data RNA pointer, and a new
function is added to get the custom data for the panel under the
cursor. This custom data could be used to refactor the "List Panel
System" to generalize it and integrate it further with RNA.
The same functionality will be added in further commits where it
applies to constraints, grease pencil modifiers, and effects.

Also, remove manually placed decorator for vertex groups in modifiers. This was
only needed because of this bug, and the layout was slightly misaligned.
Adds a wrapper-struct to create and return the three layouts required
for the propery split layout (i.e. `UILayout.use_property_split`). This
gives more flexibility for special treatment.
E.g. needed for adding the arrow icon buttons when there is a hierarchy
of nodes to be represented in the material properties (needs inserting
in the text column to not offset the split layout).
This commit also makes use of the utility for
`uiItemL_respect_property_split()`.
Usually items without labels don't use the property split layout and
just use the full layout width. In some cases that is not wanted because
it looks odd if single items within the split layout use the full width.
The option is unused but would be needed for adding decorators to the
material properties.
Previously `UILayout.prop_decorator()` (or `uiItemDecoratorR()` in C)
only worked for single items, not for arrays. The decorators are added
vertically, like `UILayout.prop()` adds them.
This will be needed for adding decorators to material properties, but
will likely have other use-cases as well.
Also, `None` (or `NULL`) can be passed for the data-pointer and property
now to create blank decorators (as already possible for
`uiItemDecoratorR_prop` in C).

We use column or row headings here to bring more structure, and to give
the eye visual anchors which aid eye-scanning. The left-aligned
checkboxes likewise help with this. And we keep the adherence to the
center line, so the alignment matches up between the various buttons and
controls.
* Changes the property split percentage from 50/50% to 40/60%. This is
needed to give enough space for the checkboxes. But in most cases this
looks better anyway - see Transform panel. In some cases it simply
fills out the available space more efficently.
* Fix various hacks where we previously used manually defined splits.
When we did this, the alignment was never quite right, and the layout
code was a mess.
* Adds column headings to many places where a list of checkboxes all
share a common purpose or leading text.
* Add checkbox + value configurations various places where a checkbox
only serves to enable the value slider
* Removes most uses of grid flow layout. The grid flow layouts combine
poorly with column headings, and also they would mess alignment up
badly. The grid flow layouts also often made buttons and controls jump
around on the screen if you would just resize editors slightly,
causing visual confusion, making users lose their place. The logic for
at what time the list of items would re-flow was often flawed, jumping
to multiple columns too fast or too late - and frankly, the grid flow
layouts would often just look bad.

Makes the following layout changes possible:
{F8473498} {F8473499} {F8473502}
The next commit will contain many layout changes to make good use of
these new possibilities. The result should be more consistent, easier to
read and should give a more organized impression. Additionally, it
should be possible to replace many sub-panels with compacter layouts.
Main changes:
* Checkboxes now respect the property split layouts
* Add support for row and column headers (i.e.
`uiLayout.column(heading="Foo")`, `uiLayout.row(heading="Bar")`). If the
first property added to this layout doesn't insert anything into the label
split column, the heading is inserted there. Otherwise, it's inserted as own
item.
* Add support for manually inserting decorators for an existing item
(`uiLayout.prop_decorator()`). That way layout creators can manually insert
this, which was the only way I saw to support property split layouts with a
checkbox before the actual property. {F8471883}
* Autogenerated layouts for operator properties look bad if there are only
checkboxes (which only use half the region width). So before creating the
layout, we iterate over visible properties and disable split layout if all
are booleans. I think this is fine, if needed we could also add layout hints
to operators.
* `uiTemplateOperatorPropertyButs()` now handles macros itself, the caller
used to be responsible for this. Code that didn't handle these so far never
used macros I think, so this change should be invisible.
* Remove manual property split layout from autogenerated operator properties
layout.
* Padding of checkboxes is tweaked to make their label visually more connected
to the checkboxes.
* Support split layout for menus (should work for `uiLayout.menu()`,
`.operator_menu_enum()`, `.prop_menu_enum()`, maybe more)

When updating the active button, the search data wasn't updated, so it
kept using the old pointers. A check in `ui_rna_collection_search_cb()`
relied on this incorrect behavior so I had to fix that too. Note that
the previous commit was also needed for the second fix to work.
Caused by c46dcdf887.
Pointer search buttons created with `uiItemPointerR()` (which allows
also passing a collection property to search in) did not work with the
split property layout (i.e. `uiLayout.use_property_split`).
For example vertex group search buttons typically use this.
Note that decorators (`uiLayout.use_property_decorate`) are not
supported yet. Although if they are enabled, the decorator column is
still created to keep the layout alignment visually intact. Also re-uses
the existing hack to allow placing multiple items in the row before the
decorator column.
Needed for some in-progress changes to the modifier stack UI.
Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

The `BKE_animsys.h` and `anim_sys.c` files already had a an "AnimData
API" section. The code in that section has now been split off, and
placed into `BKE_anim_data.h` and `anim_data.c`.
All files that used to include `BKE_animsys.h` have been adjusted to
only include the animation headers they need (sometimes none).
No functional changes.
This has some advantages over operator search:
- Some operators need options set to be usefully accessed.
- Shows key bindings to access menus
(for actions that don't have key bindings themselves).
- Non operator actions such as check-boxes are also shown.
- Menu items can control execution context, using invoke or execute
where appropriate so we can control how the operator runs.

The old convention was easy to confuse with ScrArea.
Part of https://developer.blender.org/T74432.
This is mostly a batch rename with some manual fixing. Only single word
variable names are changed, no prefixed/suffixed names.
Brecht van Lommel and Campbell Barton both gave me a green light for
this convention change.
Also ran clan clang format on affected files.
To issues caused this:
* The code to launch the filebrowser from a button didn't respect popup
menus stored in context
* There was actually no popup menu region stored in context for this
case. Doing so *may* introduce other issues, but the way I did things
already fixes all issues I've found.
`ARegion.alignment` unfortunately is a mixture of value and bitflag
enumerations. When checking for left/right/top/bottom region alignment,
the flags have to be masked out usually.
Most of the fixed cases here probably didn't cause issues in practice,
but could in fact break at any point when surrounding logic changes.
In fact the assert in #region_visible_rect_calc() failed in an older
file from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=949035. This
fixes it.
Adds a `text` parameter to `bpy.types.uiLayout.template_ID()` which
causes a label to be added, as usual. Adding the label also makes the
template respect the `bpy.types.uiLayout.use_property_split` option.
Also fixes wrong layout being used in the template-ID, although I think
that didn't cause issues in practice.
Sergey requested this for usage in the Movie Clip Editor.
