This was due to a missing endpoint case that wasn't handled in the port.
The last point still have to be discarded manually because of the
dot/stroke setting of the material.
The first test `ma1.x == -1` is not necessary anymore since the index
buffer do not contain this point (which was rendered using instance
rendering before.

Unlike other (closed) hierarchies, view layers dont show their contents
next to their names.
Code would still find the item via outliner_find_item_at_x_in_row though,
this is now prevented (same as if the viewlayer was open [instead of
collapsed]).
Fixes T102357.

This patch implements the Streaks Glare node. Which is an approximation
to the existing implementation in the CPU compositor. The difference due
to the approximation is bearily visible in artificial test cases, but is
less visible in actual use cases. Since the difference is rather similar
to that we discussed in the Simple Star mode, the decision to allow that
difference would probably hold here.
For the future, we can look into approximating this further using a
closed form IIR recursive filter with parallel interconnection and
block-based parallelism. That's because the streak filter is already
very similar to the causal pass of a fourth order recursive filter,
just with exponential steps.

This patch implements the variable size mode of the blur node. This is
not identical to the CPU implementation, but is visually very close.
That's because of two things. First, the Extend Bounds option introduces
a 2px offset that doesn't make sense, which is likely a bug in the CPU
implementation. Second, the CPU implementation approximate the result
using three passes, the first two of which are separable morphological
operators applied on the size input. But this approximation does not
provide an advantage because the last pass is non-separable anyways. So
the GPU implementation does not attempt this approximation for more
accurate and faster results.

This simplifies some memory management, ammortizes some of the many
small allocations when building UI layouts, and simplifies the code
that deals with the groups. `uiBlock` is no longer a trivial type.
In my testing this saved a few ms when drawing a large node tree.
Duplicating context lists took a measurable amount of time when drawing
large node trees in the node editor. Instead of using a linked list of
entries, which results in many small allocations, use a vector. Also,
use std::string and StringRefNull instead of char buffers and pointers.
I had forgotten about curves sculpt mode when I wrote
this function. It just initializes the viewport
pivot point to the evaluated object bounding box.
Should be used inside the mode entry function.
Texpaint now bounds checks material indices when looking up
materials, in case the user has corrupted the material_index
attribute somehow. We may wish to report this to the user
somehow on entering texture paint mode.
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.
Re-apply [1] & [2], revert [3] & [4].
