This commit removes the outline from instances generated from an object
when in edit mode. This takes the change in aa13c4b386 a bit further,
with the idea that instance outlines are more like regular outlines.
Because evaluated object data that doesn't match the original object
type is treated as an instance internally, this fixes the way evaluated
meshes for curves objects have an outline, for example.
See the differential revision for a visual comparison.

There are two issues revealed in the bug report:
- the GPU subdivision does not support meshes with only loose geometry
- the loose geometry is not subdivided
For the first case, checks are added to ensure we still fill the
buffers with loose geometry even if no polygons are present.
For the second case, this adds
`BKE_subdiv_mesh_interpolate_position_on_edge` which encapsulates the
loose vertex interpolation mechanism previously found in
`subdiv_mesh_vertex_of_loose_edge`.
The subdivided loose geometry is stored in a new specific data structure
`DRWSubdivLooseGeom` so as to not pollute `MeshExtractLooseGeom`. These
structures store the corresponding coarse element data, which will be
used for filling GPU buffers appropriately.

previously_visible_components_mask was not preserved for Image ID nodes, which
meant it was always detected as newly visible and tagged to be updated, which
in turn caused the geometry nodes using it to be always updated also.

A simple case of missing the tangent VBO. The tangents are computed from
the coarse mesh, and interpolated on the GPU for the final mesh. Code for
initializing the tangents, and the vertex format for the VBO was
factored out of the coarse extraction routine, to be shared with the
subdivision routine.
Mousemove events are sent to windows.
In Windows OS, almost all mousemove events are sent to the window whose
mouse cursor is over.
On MacOS, the window with mousemove events is always the active window.
It doesn't matter if the mouse cursor is inside or outside the window.
So, in order for non-active windows to also have events,
`WM_window_find_under_cursor` is called to find those windows and send
the same events.
The problem is that to find the window, `WM_window_find_under_cursor`
only has the mouse coordinates available, it doesn't differentiate
which monitor these coordinates came from.
So the mouse on one monitor may incorrectly send events to a window on
another monitor.
The solution used is to use a native API on Mac to detect the window
under the cursor.
For Windows and Linux nothing has changed.

The issue was uncovered by the 0f89bcdbeb, but the root cause goes
into a much earlier design violation happened in the code: the modifier
evaluation function is modifying input mesh, which is not something
what is ever expected.
Bring code closer to the older state where such modification is only
done for the object in edit mode.

From own tests works seems to work fine, but extra eyes and testing

The image engine is depth aware when using tile drawing the depth is
only updated for the central image what lead to showing the background
on top of other areas.
Also makes sure that switching the tile drawing would lead to an update
of the texture slots.
When dimension of images aren't a multifold of 256 parts of the gpu
textures are not updated. This patch will calculate the correct part of
the image that needs to be reuploaded.
Internally the update tiles are 256x256. Due to some miscalculations
tiles were not generated correctly if the dimension of the image wasn't
a multifold of 256.
Previously we used to cache a float image representation of the image in
rect_float. This adds some incorrect behavior as many areas only expect
one of these buffers to be used.
This patch stores float buffers inside the image engine. This is done per
instance. In the future we should consider making a global cache.
New code from the vertex normal refactor cfa53e0fbe combined with older code
from 592759e3d6 that disabled instancing for custom normals and autosmooth
meant that instancing was always disabled.
However we do not need to disable instancing for custom normals and autosmooth
at all, this can be shared between instances just fine.
Caused by 0f89bcdbeb and was not fully addressed by 6f9828289f:
tagging an ID with flag 0 is to be seen as an explicit tag for copy
on write.
Would be nice to either consolidate code paths of flag 0 and explicit
component tag, or get rid of tagging with 0 flag, but that is above of
what we can do for the upcoming release.
When using ancored stroked the diameter of the stroke can be 0 what
leads to a division by zero that on certain platforms wrap to a large
negative number that cannot be looked up. This fix will clamp the size
of the brush to 1.
In some cases, the normal edit modifier calculated the normals on one
mesh with the "ensure" functions, then copied the mesh and retrieved
the layers "for write" on the copy. Since 59343ee162, normal
layers are never copied, and normals are allocated with malloc instead
of calloc, so the mutable memory was uninitialized.
Fix by calculating normals on the correct mesh, and also add a warning
to the "for write" functions in the header.
The check to see if newly requested attributes are not already in the
cache was not taking into account the possibility that we do not have
new requested attributes (`num_requests == 0`). In this case, if
`attr_used` already had attributes, but `attr_requested` is empty, we
would consider the cache as dirty, and needlessly rebuild the attribute
VBOs.
These features are complicated to support on GPU and hardly compatible
with subdivision in the first place. In the future, with T68891 and
T68893, subdivision and custom smooth shading will be separate workflows.
For now, and to better prepare for this future (although long term
plan), we should discourage workflows mixing subdivision and custom
smooth normals, and as such, this disables GPU subdivision when
autosmoothing or custom split normals are used.
This also adds a message in the modifier's UI to indicate that GPU
subdivision will be disabled if autosmooth or custom split normals are
used on the mesh.

Reuse the same vertex normals calculation as for the GPU code, by
weighing each vertex normals by the angle of the edges incident to the
vertex on the face.
Additionally, remove limit normals, as the CPU code does not use them
either, and would also cause different shading issues when limit surface
is used.
Fixes T95242: shade smooth artifacts with edge crease and limit surface
Fixes T94919: subdivision, different shading between CPU and GPU
This operation can only be applied on one ID at a time, so only apply it
to the active Outliner item, and not all the selected ones.
Also renamed `Make Library Override` menu entry to `Make Library Override
Single` to emphasis this is not the 'default expected' option for the
user.
Trust user count to actually delete or not the dragged ID when current
dragging is cancelled, since it may be already used by others.
NOTE: This is more a band-aid fix than anything else, cancelling drag
has a lot of other issues here (like never deleting any indirectly
linked/appended data, etc.). It needs a proper rethink in general.
To keep consistency with the new contract option, the dilate now expand the shape beyond the internal closed area.
Note: This was committed only in master (3.2) by error.
This is requested by artist for some animation styles where is necessary to fill the area, but create a gap between fill and stroke.
Also some code cleanup and fix a bug in dilate for top area.

Note: This was committed only in master (3.2) by error.
Without ray offsets intersections at neigbhoring triangles are found, as
the ray start is exactly at the vertex. There was a small offset towards
the center of the triangle, but not enough.
Now this offset computation is moved into Cycles and modified for better
results. It's still not perfect though like any offset approach, especially
with long thin triangles.
Additionaly, this uses the shadow terminate offset for AO rays now, which
helps remove some pre-existing artifacts.
Also fix a couple other places where normals layers weren't properly
tagged dirty or reallocated when the mesh changes.
Caused by cfa53e0fbe. When the size of a mesh changes,
the normal layers need to be reallocated. There were a couple of places
that cleared other runtime data with `BKE_mesh_runtime_clear_geometry`
but didn't deal with normals properly. Clearing the runtime "geometry"
is different from clearing the normals, because sometimes the size of
the normal layers doesn't have to change, in which case simply tagging
them dirty is fine.
When X-ray mode is active the selection is done using the mesh data to
select what is closest to the cursor. When GPU subdivision is active with
the "show on cage" modifier option, this fails as the mesh used for selection
is the unsubdivided one.
This creates a subdivision wrapper before running the selection routines to
ensure that subdivision is available on the CPU side as well.

This was a double free error which happened because `BM_mesh_bm_from_me`
was taking ownership of arrays that were still owned by the Mesh. Note that
this only happens when the mesh is empty but some custom data layers still
have a non-null data pointer. While usually the data pointer should be null in
this case for performance reasons, other functions should still be able to
handle this situation.

When exporting generated coordinates, the subdivision export code was
using the schema for the non-subdivision case, which is invalid as
non-initialized. This typo existed since the initial commit for the
