That max number of `10000` level of recursivity was a typo (should have
been `1000`), but even that is way too high, typical sane situation
should not lead to more than a few tens of levels, so reducing the max
level to 200.
Also improve error message with more context info about the issue.
Found while investigating issues for the Blender Studio's Heist production.
In some cases (when there is an evaluated curve), the conversion code
would try to free the evaluated data-block twice, because freeing the
object would free it from `data_eval` and then the data-block was freed
again explicitly. Now check if the data-block is stored in `data_eval`
before freeing `object.data` manually. This is another area that's made
more complex by the fact that we change the meaning of `object.data`
for evaluated objects. The solution is more complicated than it should
be, but it works whether or not an evaluated mesh or curve exists.
It wasn't possible to temporarily orbit the view, then set back to an
axis-aligned view.
Details:
- It was possible to change RegionView3D.view_rotation while the view
kept the axis alignment value (Top, Left, Front .. etc) which
displayed in the viewport overlay.
Now changing the view rotation directly or via "view_matrix" resets
the axis-alignment - clearing when the view is no longer axis-aligned
or assigning the newly aligned axis.
- RegionView3D.is_orthographic_side_view added in [0] could be assigned
but wasn't useful as it treated an enum as a boolean only setting the
RegionView3D.view to RV3D_VIEW_USER or RV3D_VIEW_FRONT.
Now enabling this aligns the viewport rotation to it's closest
axis-aligned orientation setting RegionView3D.view & view_axis_roll
accordingly. Note that the "orthographic" term is misleading as the
property only relates to axis-alignment, not to the
perspective/orthographic setting. We could consider deprecating the
current naming.

View roll checked if the resulting roll was close to a view axis
but didn't write the aligned quaternion back to the final result.
Add ED_view3d_quat_to_axis_view_and_reset_quat since most callers
to ED_view3d_quat_to_axis_view will reset the quaternion when a view
aligned axis is found.
Issue revealed by rB90e12e823ff0. Hidden objects may not be fully
evaluated by the despgraph, do not attempt to restore edit/sculpt/etc.
modes for those.
Should also be backported to 2.93 LTS release.
Sometimes integers are mixed using float weights. In those cases
the mixed result has to be converted from into float again.
Previously, this was done using a simple cast, which was unexpected
because e.g. 14.999 would be cast to 14 instead of 15.
Now, the values are rounded properly.
This can affect existing files unfortunately without a good option
for versioning. Gladly, very few files seem to depend on the details
of the old behavior.

This makes changes to the opensubdiv module to support additional vertex data
besides the vertex position, that is smootly interpolated the same way. This is
different than varying data which is interpolated linearly.
Fixes T96596: wrong generated texture coordinates with GPU subdivision. In that
bug lazy subdivision would not interpolate orcos.
Later on, this implementation can also be used to remove the modifier stack
mechanism where modifiers are evaluated a second time for orcos, which is messy
and inefficient. But that's a more risky change, this is just the part to fix
the bug in 3.2.

Previously, the depsgraph assumed that every node tree might contain
a reference to a video. This resulted noticeable overhead when there
was no video.
Checking whether a node tree contained a video was relatively expensive
to do in the depsgraph. It is cheaper now due to the structure of the new
node tree updater.
This also adds an additional run-time field to `bNodeTree` (there are
quite a few already). We should move those to a separate run-time
struct, but not as part of a bug fix.

If making liboverride of an empty collection, this (root of override
hierarchy) collection would get untagged in code when checking for
collections that do not need to be overridden, leading to not overriding
this root collection, and later in code to using NULL pointer.
Regression caused by [0] which changed node selection to use
PRESS for selection and CLICK_DRAG to transform the selection.
This conflicted with Alt-LMB which would select the node then
pass-though to node.background_sample, preventing the drag event
from being activated.
Resolve by only activating background-sample when the cursor
isn't over a node or socket.

Issue was caused by treating such strip as meta and using
`seq->channels` directly, which is not valid for scene strips.
Pointer to channels is now provided by function
`SEQ_get_seqbase_from_sequence`.
We need to ensure `Main.filepath` is consistent with the current path
where we are saving the .blend file, otherwise some path processing code
can produce invalid results (happens with e.g. the code syncing the two
path storages in Library IDs).
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.
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

crash on undo/redo.
Reworked the code instantiating that extra collection in a more generic
and hopefully robust way now.
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.

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.
