The problem is that depsgraph evaluation happens before the OpenGL context
is initialized, and so modifier evaluation happens without GPU subdivision.
Later the BKE_subsurf_modifier_can_do_gpu_subdiv test in the draw code gives
a different result.
This just checks if the mesh has information for GPU subdivision in the draw
code, and if so uses it. This is only set if the test for supported GPU
subdivision passes in the modifier evaluation.
Additionally it may be good to perform OpenGL context initialization earlier
so background render can take advantage of GPU subdivision, but this is more
complicated.

A regression since 113b8030ce: circle selection operators does not
define properties like deselect_all and a special name callback is to
be used for those.
This is what was already done for circle select in the 3D viewport.
Some other spaces were using the generic pick operator for the circle
selection which causes error prints in the console.
Regression in tests from [0] tests were written to assume a newline was
added to the result of Text.as_string which is no longer the case.

Refactoring event click-drag detection broke click detection for
simulated events. Resolve this by sharing logic for update previous
values in `wmWindow.eventstate` for regular event handling
(no functional changes for non-simulated events). Failure to detect
clicks for simulated events broke the undo test
`test_undo.view3d_multi_mode_select` in `../lib/tests/ui_simulate/run.py`.
All undo tests now pass.
Moving Text.as_string() from Python to C [0] added an extra new-line
causing a round-trip from_string/to_string to add a new-line,
this also broke the undo test `test_undo.text_editor_simple` in
`../lib/tests/ui_simulate/run.py`.

Fix a crash when a driver variable targets an object and uses
`data.shape_keys.key["name"].value` in its expression.
The fix consists of adding an extra relation from the targeted object's
`GEOMETRY` component to the driver evaluation. This ensures that its
`data` pointer has been evaluated by the depsgraph and is safe to
follow.
This also resolves the concern raised on rB56407432a6aa.

The 'OVERRIDE_HIDDEN' extra collection would often be mistakenly added
to a linked collection, which is totally forbidden and guaranteed to
crash on undo/redo.
Reworked the code instantiating that extra collection in a more generic
and hopefully robust way now.
Made tangent frame consistent across the surface regardless of the sample,
which was not the case with the previous algorithm. Previously, a tangent
frame would stay consistent for the same sample throughout the walk, but not
from sample to sample for the same triangle. This actually resulted in code
simplification.
Also includes additional fixes:
* Fixed an important bug that manifested itself with multiple lights in the
scene, where caustics had abnormally low amplitude: The final light pdf did
not include the light distribution pdf.
* Removed unnecessary orthonormal basis generation function, using cycles'
native one instead.
* Increased solver max iteration back to 64: It turns out we sometimes need
these extra iterations in cases where projection back to the surface takes
many steps. The effective solver iteration count, the most expensive part,
is actually much less than the raw iteration count.

We really need to fix how unprojected radius (scene unit) works.
What happened is the paint code updates the brush's normal radius
with the current unprojected pixel radius, which was then
used by texture brush tiled mode.
To fix this I just cached the pixel radius at stroke start in
UnifiedPaintSettings->start_pixel_radius.
This was due to using `BKE_scene_has_object` function, which uses the
cache of bases of the viewlayers, which do not have entries for the
content of excluded collections... Now use
`BKE_collection_has_object_recursive` instead.
Steps to reproduce were:
- Factory startup
- Right-click in 3D View
- Move the mouse over "Shade Flat", wait for the tooltip
The changed logic in 4680331749 to lookup an active button was
incorrect. It didn't respect the priority of active button candidates.
Issue is that the operator acts on the active button, and also uses that in the
poll. So the actually active button would affect the poll of a different
button. For the superimposed icons we need to be able to execute these polls
properly for non-active buttons.
This enables temporarily overriding the active button for lookups via context.
While a bit of a hack it makes sense conceptually.

Regression caused by [0] which made `ui_but_is_interactive` consider
label buttons with tool-tips to be interactive. This prevented
the clicks to pass through to the nodes for selecting/dragging.
Resolve this by allowing buttons to be activated for the purpose
of showing tool-tips but otherwise considering them disabled
(as if the UI_BUT_DISABLED is set when handling events).

When extracting UV point indices, only the vertex points coming from the
original geometry should be drawn. For this, the routines (for subdivision
and coarse meshes) would only consider a vertex to be real if the extraction
type is `MAPPED`, and that an origin index layer on the vertices exist
with a valid origin index for the current vertex.
However, if the extraction type is `MESH`, which can happen with for
example an empty Geometry Node modifier, or with deferred subdivision,
this would consider every vertex to not be "real" and therefore hidden from
the UV editor.
This reworks the condition for "realness" to also consider a vertex to be
real if there is no origin layer on the vertices. The check on the extraction
type is removed as it becomes redundant.
This only modifies the check in the UV data extraction for point indices,
however similar checks exist throughout the extraction code, these will
be dealt with separately in master.

This abuse of one one size value to handle another allocated array of a
different size is bad in itself, but at least now read/write code of
this modifier should not risk invalid memory access anymore.
NOTE: invalid memory access would in practice only happen in case endian
switch would be performed at read time I think (those switches only check
for given length being non-zero, not for a NULL data pointer...).
This was because the main `surface_vert.glsl` was changed to accomodate the
needs of the `ShaderCreateInfo` but was still used by the cryptomatte
shader. The fix is to include the same libraries as the material shaders
and bypass `attrib_load()`.
This was caused by the `mb_data->obmat[]` being wrong because they are
now shared between the particle system and the object.
But Hair need the dupli parent matrix instead of the object matrix.
Disabling `Show Emitter` option fixes the bug.
To avoid this problem, request a different `EEVEE_ObjectMotionData`
for particle systems using a different key pointer in the hash.
This is a bit dirty but there is less code polution using this workaround.

There are two problems when adding a paint slot to an object without an
existing material. First, the `invoke` method creates a material on the
object. This modifies the object even if the operation is not executed.
Second, the fill color defaults to black when there is no existing
material (even when adding a normal, bump, or displacement layer).
This patch moves the material creation to the `exec` method.
When no material exists on the object, a default Principled BSDF is
referenced for default colors in the `invoke` method.

If merging is enabled, the mesh might be recreated before
the dirty flag can be cleared, which means the normals aren't
valid anymore. To fix this, clearing the dirty flag should happen
before the merging. This is an existing bug, just exposed by
more recent explicit dirty normal tagging.
In rare cases the mesh has not been evaluated when snapping, this fix
just prevents the crash as is done elsewhere in Blender when the
evaluated mesh isn't available, there is a separate report (T96536)
about evaluation not working properly.
Now add a default ".usdc" file extension if no (or the wrong) extension
is given instead of presenting the user with the error that "no suitable
USD plugin to write is found".
This is in line with how other exporters do this.

This patch checks if the number of compute ssbo blocks matches

Some platforms allow more ssbo bindings then blocks per stage.
Geometry nodes can generate color attributes that aren't on point or corner domain.
When not found in these domains it will be processed as a common attribute.
