The Grease Pencil Material Popover currently has a color picker
for the Stroke of a Material using Solid style, but not one for
a Fill using Solid style.
With the default Grease Pencil Materials, the current
popover only shows the Stroke color for the grey "Solid Fill"
material (which doesn't have its Stroke enabled) instead of
the more useful Fill color.
This patch shows a Stroke color picker when the Material
has Stroke enabled and the style is Solid.
This is the same for the Fill.

A proper boolean custom property type is commonly requested. This
commit simply adds a new `IDP_BOOLEAN` type that can be used for
boolean and boolean array custom properties. This can also be used
for exposing boolean node sockets in the geometry nodes modifier.
I've just extended the places existing IDProperty types are used, and
tested with the custom property edit operator and the python console.
Adding another IDProperty type is a straightforward extension of the
existing design.

Currently the `MLoopUV` struct stores UV coordinates and flags related
to editing UV maps in the UV editor. This patch changes the coordinates
to use the generic 2D vector type, and moves the flags into three
separate boolean attributes. This follows the design in T95965, with
the ultimate intention of simplifying code and improving performance.
Importantly, the change allows exporters and renderers to use UVs
"touched" by geometry nodes, which only creates generic attributes.
It also allows geometry nodes to create "proper" UV maps from scratch,
though only with the Store Named Attribute node for now.
The new design considers any 2D vector attribute on the corner domain
to be a UV map. In the future, they might be distinguished from regular
2D vectors with attribute metadata, which may be helpful because they
are often interpolated differently.
Most of the code changes deal with passing around UV BMesh custom data
offsets and tracking the boolean "sublayers". The boolean layers are
use the following prefixes for attribute names: vert selection: `.vs.`,
edge selection: `.es.`, pinning: `.pn.`. Currently these are short to
avoid using up the maximum length of attribute names. To accommodate
for these 4 extra characters, the name length limit is enlarged to 68
bytes, while the maximum user settable name length is still 64 bytes.
Unfortunately Python/RNA API access to the UV flag data becomes slower.
Accessing the boolean layers directly is be better for performance in
general.
Like the other mesh SoA refactors, backward and forward compatibility
aren't affected, and won't be changed until 4.0. We pay for that by
making mesh reading and writing more expensive with conversions.

**Changes**
As described in T93602, this patch removes all use of the `MVert`
struct, replacing it with a generic named attribute with the name
`"position"`, consistent with other geometry types.
Variable names have been changed from `verts` to `positions`, to align
with the attribute name and the more generic design (positions are not
vertices, they are just an attribute stored on the point domain).
This change is made possible by previous commits that moved all other
data out of `MVert` to runtime data or other generic attributes. What
remains is mostly a simple type change. Though, the type still shows up
859 times, so the patch is quite large.
One compromise is that now `CD_MASK_BAREMESH` now contains
`CD_PROP_FLOAT3`. With the general move towards generic attributes
over custom data types, we are removing use of these type masks anyway.
**Benefits**
The most obvious benefit is reduced memory usage and the benefits
that brings in memory-bound situations. `float3` is only 3 bytes, in
comparison to `MVert` which was 4. When there are millions of vertices
this starts to matter more.
The other benefits come from using a more generic type. Instead of
writing algorithms specifically for `MVert`, code can just use arrays
of vectors. This will allow eliminating many temporary arrays or
wrappers used to extract positions.
Many possible improvements aren't implemented in this patch, though
I did switch simplify or remove the process of creating temporary
position arrays in a few places.
The design clarity that "positions are just another attribute" brings
allows removing explicit copying of vertices in some procedural
operations-- they are just processed like most other attributes.
**Performance**
This touches so many areas that it's hard to benchmark exhaustively,
but I observed some areas as examples.
* The mesh line node with 4 million count was 1.5x (8ms to 12ms) faster.
* The Spring splash screen went from ~4.3 to ~4.5 fps.
* The subdivision surface modifier/node was slightly faster
RNA access through Python may be slightly slower, since now we need
a name lookup instead of just a custom data type lookup for each index.
**Future Improvements**
* Remove uses of "vert_coords" functions:
* `BKE_mesh_vert_coords_alloc`
* `BKE_mesh_vert_coords_get`
* `BKE_mesh_vert_coords_apply{_with_mat4}`
* Remove more hidden copying of positions
* General simplification now possible in many areas
* Convert more code to C++ to use `float3` instead of `float[3]`
* Currently `reinterpret_cast` is used for those C-API functions

There are two underlying issues which got uncovered by the report:
First, is that the poll() function for the operator was using legacy
API which is on its way of removal in the next major version release.
This part is fixed in this patch based on a patch provided by Philipp
Oeser (P3389) with the modification that the `clip` is not accessed
prior to None check. Ended up in a bit annoying one-liner, the entire
function could be refactored to use early returns.
The second issue is that the Python access to the legacy property
was wrong: need to access camera reconstruction instead of accessing
deprecated DNA field.

[[ https://blenderartists.org/t/cant-create-new-layers-in-grease-pencil-dopesheet/1353882 | Can’t create new layers in grease pencil dopesheet ]]
This is often because the 'Only Show Selected' filter is disabled. This 'requirement' does not seem to be necessary since the Dopesheet is already in Grease Pencil mode and there is an active Grease Pencil Object. It is also not apparent as to why so many Operators depend on it and unintuitive that it controls their function. The 'Only Show Selected' filter button is far away from the Operator buttons in the User Interface Header, so it's difficult to make the association.
If the 'Only Show Selected' IS absolutely required, I believe it should be closer to the DOPESHEET_HT_editor_buttons. Otherwise, I think the requirement should be removed.

Remove the option to display the real size of the cursor
and set as default. Now the cursor is displayed or not using
show_cursor option, but if it's displayed always use the real size.
This patch makes sure that each of the expand keymap entries will use consistent "invert" and "use_mask_preserve" properties.
Based on previous discussions we decided to flip the default Mask Expand behavior.
This has multiple benefited:
- The mask creation is more consistent with other masking tools (Always add to existing mask. Mask selected areas)
- It's easier to use expanding for masking face sets (Snapping with `Ctrl`) or building a mask from repeated operations
- It's less likely to mask certain areas unintentionally (Loose mesh islands)
- If the current behavior is desired for an expand operation the user can use `E` & `F` in the modal keymap (Which is less often the case).
If we want to revisit the original design of inverted masking again in the future we should do this via {T97903}.
