Partially addresses T72011.
The problem here is that the previous barycentric clamping did not deal well
with skinny triangles and would end up generating "sub-pixel jittering"
locations that were actually >20 pixels away.

Previously, the code tried to keep node groups working even if some of
their input/output sockets had undefined type. This caused some
complexity with no benefit because not all places outside of this file
would handle the case correctly. Now node groups with undefined
interface sockets are disabled and have to be fixed manually before
they work again.
Undefined interface sockets are mostly caused by invalid Python
API usage and incomplete forward compatibility (e.g. when newer
versions introduce new socket types that the older version does
not know).
Avoid utility function call that would query the file system, this was a
bottleneck. The path joining was also problematic. See patch for more
details.

Materials without connections to the output node would crash with OSL
in OptiX, since the Cycles `OSLCompiler` generates an empty shader
group reference for them, which resulted in the OptiX device
implementation setting an empty SBT entry for the corresponding direct
callables, which then crashed when calling those direct callables was
attempted in `osl_eval_nodes`. This fixes that by setting the SBT entries
for empty shader groups to a dummy direct callable that does nothing.
Switching viewport denoising causes kernels to be reloaded with a new
feature mask, which would destroy the existing OptiX pipelines. But OSL
kernels were not reloaded as well, leaving the shading pipeline
uninitialized and therefore causing an error when it is later attempted to
execute it. This fixes that by ensuring OSL kernels are always reloaded
when the normal kernels are too.
Restrict the condition under which paint cursors read use the cursor
location from the the operating-system.
This caused a glitch when dragging UI elements in painting context
popup. Since the paint cursor would display using mouse motion
which was clamped to the window center - an internal detail of hidden
cursor grabbing.
Now only read the cursor coordinates when clamped to a region which
is used for the transform cursor to stay visible even when the cursor
wraps around.
Recent reverting of changes to cursor grabbing intended to match
Blender 3.3 release. This is the case for 3.4x branch, however there is
an additional change to grabbing on WIN32 by Germano [0] which is a
significant improvement on old grabbing logic for Windows.
So instead of matching 3.3x behavior, restore logic that keeps
the cursor centered while grabbing & hidden.
This re-introduces T102792 issue displaying the paint-brush while
dragging buttons, this will have to be solved separately.

The paint cursor was continuously set which meant hiding the cursor
while interacting with buttons would immediately show it again.
This exposed cursor warping.
Small roundoff errors during UV editing can sometimes occur, most likely
due to so-called "catastrophic cancellation".
Here we set a tolerance around zero when using Constrain-To-Bounds and UV Scaling.
The tolerance is set at one quarter of a texel, on a 65536 x 65536 texture.
TODO: If this fix holds, we should formalize the tolerance into the UV editing
subsystem, perhaps as a helper function, and investigate where else it needs
to be applied.

Attributes are unifying around a name-based API, and we would like to
be able to move away from CustomData in the future. This patch moves
the identification of active and fallback (render) color attributes
to strings on the mesh from flags on CustomDataLayer. This also
removes some ugliness used to retrieve these attributes and maintain
the active status.
The design is described more here: T98366
The patch keeps forward compatibility working until 4.0 with
the same method as the mesh struct of array refactors (T95965).
The strings are allowed to not correspond to an attribute, to allow
setting the active/default attribute independently of actually filling
its data. When applying a modifier, if the strings don't match an
attribute, they will be removed.
The realize instances / join node and join operator take the names from
the first / active input mesh. While other heuristics may be helpful
(and could be a future improvement), just using the first is simple
and predictable.

If the resulting geometry from applying a geometry nodes modifier
contains no mesh, give an error message. This gives people something to
search and makes the behavior more purposeful.
Also remove the `modifyMesh` implementation from the geometry nodes
modifier, since it isn't necessary anymore. And remove the existing
"Modifier returned error, skipping apply" message which was cryptic
and redundant if applying returns an actual error message.
Resolves T103229

This patch allows skipping the automatic insertion of nodes on top of
links when the transform operator ends. When putting nodes into small
spaces this often gets in the way and wastes time. Now, when holding
`alt`, this is turned off.
The header text is also improved to add this shortcut and to remove
the Dx and Dy values and improve the formatting a bit.
Making this functionality optional might allow us to use it in more
places in the future, like for the nodes added by link-drag-search.

The function was highly related to the apply modifier operator,
and only used once. This was too specific to be in the blenkernel,
especially in a mesh conversion file.
