Previously, multiple threads adding information to node ui storage
at the same time resulted in memory corruption. The lock prevents
that, but might potentially become a bottleneck in the future.
For now favour correctness over a potential performance bottleneck.
Not allowing external direct access to the vector of splines in the
curve will help for things like reallocating custom data when a spline
is added or removed.
This commit exposes the first spline control point attributes. The
implementation incorporates the attributes into the virtual array
system, providing efficient methods to flatten the data into a
contiguous array and to apply changes from a flattened array. This
is only part of the eventual goal, which includes changes to run
attribute nodes separately for each spline to completely avoid copying.
So far `tilt` and `radius`, the two generic attributes common to
all spline types, are implemented. The more complex `position`
attribute is also added. It requires some special handling for Bezier
splines, where the control point handles need to be moved along with
the control points. To make that work I also added automatic handle
recalculation to the Bezier spline.

With Constrain to Image Bounds selected, UVs will be constrained to the
correct/closest UDIM if the image is tiled.
UVs will be constrained to the 0-1 UV space if the image is not tiled.
This will override the present behavior of always constraining selected
UVs to the 0-1 UV space (UDIM 1001).

Extracts `nlasnapshot_blend_get_inverted_upper_snapshot()` from
`BKE_animsys_nla_remap_keyframe_values()`
This introduces a new struct member:
`NlaEvalChannelSnapshot->remap_domain` and marks which values of
`blended_snapshot` are processed for remapping/used-for-inverting.
Effectively, it marks which values have successfully been remapped and
can be further used for remapping.
`nlasnapshot_blend_get_inverted_upper_snapshot()`:
output snapshot `r_upper_snapshot` has each channel's `remap_domain`
written to which effectively marks the successfully remapped values.
The only reason a value is not in the remap domain is if inversion
failed or it wasn't marked to be remapped.
`..get_inverted_upper_snapshot()` has a variant `nlasnapshot_blend()`
from {D10220}, but this patch doesn't depend on it at all. A third
variant will later be added `..get_inverted_lower_snapshot()`.
Altogether, these three functions allow solving for any of
(lower_snapshot, upper_snapshot, blended_snapshot) given the other two.
The function `..get_inverted_lower_snapshot()` will also similarly
process the remap domain of the blended and lower snapshot.
added assertions within `nlasnapshot_blend()` and
`..get_inverted_upper_snapshot()` to future proof branches dealing with
blendmode and mixmodes. (suggested by sybren)

The last point of the output was at the same location as the
first point of a cyclic spline. The fix is simple, just account for
the cyclic when choosing the sample edge length, and don't
hard code the last sample.
The spline `length` function assumed that the curve always had evaluated
edges. That is clearly false. This commit adds a check to `length` and a
special case for a single point in the curve resample node.
This commit uses two changes to improve the performance of the point
instance node.
**Prevent Reallocations**
At 64 bytes, the transform matrix for every instance is rather large,
so reallocating the vector as it grows can become a performance bottle-
neck. This commit reserves memory for the instances that will be added
to prevent unecessary reallocations as the instance vector grows.
In a test with 4 million instances of 3 objects in a collection, the
node was about 40% faster, from 370ms to 270ms for the node.
**Parallelization**
Currently the instances are added by appending to a vector. By changing
this slightly to fill indices instead, we can parallelize the operation
so that multiple threads can fill data at the same time. Tested on a
Ryzen 3700x, this reduced the runtime from the above 270ms to 44ms
average, bringing the total speedup to ~8x.
Note that displaying the instances in the viewport is still much slower
than the calculations in node, this change doesn't affect that.
Those were mostly just left over from previous work on particle nodes.
They solved the problem of keeping a reference to an object over
multiple frames and in a cache. Currently, we do not have this problem
in geometry nodes, so we can also remove this layer of complexity
for now.
We need to always add a single point to the last cyclic segment that
completes the loop, because that includes the starting point of the
evaluated edge. The existing code forgot about that point.
This node generates a naturally parametarized (even length edge) poly
spline version of every spline in the input. There are two modes,
"Count", and "Length". These are similar to the same options for the
line primitive node in end points mode.
I implemented this instead of a "Sample Points" node, because for this
operation it's trivial to keep the result as a curve, which is nice
since it increases flexibility, and because it can make instancing
simpler, i.e. using the transforms of each evaluated point rather than
requiring the construction of a "rotation" attribute.

We were not assigning the amount of sound channels to the output frames.
Newer ffmpeg releases has sanity checks in place and doesn't fall back
to two channels anymore.
this is a followup to rB2bd85d9cc623, we cannot forcefully delete
obsolete overrides of object data (meshes etc.), as this implies also
deleting their user object, which might still be a perfectly valid
override, albeit in conflict regarding its obdata ID pointer...
This is the opposite of previous code, which would keep those
'deprecated' overrides arround (often in a dedicated collection), when
they were detected as user-edited.
While this is a safe-ish way to (try to) preserve user-edited data, this
tends to add too much 'trash' data to production scenes, which cleaning
becomes a burden.
Note that user will get warnings in thos cases, and can always choose
not to save the current blend file and go fix the library issue instead.
Code detecting overrides which reference linked data is missing was
actually missing many cases, leading to too much garbage data being kept
around after resync process.
This node has the same functionality as the color and vector curve
mapping nodes in the shader editor. Here is works on every value for
the selected attribute, and it can also output a float value. Other
than that, the implementation is quite straightforward-- almost
completely boilerplate code.

Fix trying to use cross product on parallel vectors.
Fix intersection checks failing because we run into floating point

One of current annoying limitations of Blender re Collections/Objects is
that objects are forbidden to not be instantiated in at least one
collection.
Code ensuring that as a pst-processing step of override creation/resync
operations would be a bit too eager to add those objects to an external
'ad-hoc' collection, which poses several issues (both in term of keeping
the scene well organized, and related to override hierarchy handling).
So now be very conservative and only generate and use external 'storage'
collection for those objects when it is absolutely mandatory.
In pratice, it means this should never happen anymore on any decently
organized data source.
Caused by {rB0d9f79b163ee}.
IDP_SyncGroupTypes was now syncing from src to src (leading to
unexpected operator properties).
Assume this is rather critical, dont know the part of the code well, but
above commit clearly shows a change from 'dest->data.group' to 'src-
>data.group' which shouldnt be there.
