This just adds `threading::parallel_for` and `threading::parallel_invoke` in a few
places where it can be added trivially. The run time of the `separate_geometry`
function changes from 830 ms to 413 ms in my test file.

Add a new node that groups faces inside of boundary edge regions.
This is the opposite action as the existing "Face Group Boundaries"
node. It's also the same as some of the "Initialize Face Sets"
options in sculpt mode.
Discussion in #102962 has favored "Group" for a name for these
sockets rather than "Set", so that is used here.

As described in #95966, replace the `ME_EDGEDRAW` flag with a bit
vector in mesh runtime data. Currently the the flag is only ever set
to false for the "optimal display" feature of the subdivision surface
modifier. When creating an "original" mesh in the main data-base,
the flag is always supposed to be true.
The bit vector is now created by the modifier only as necessary, and
is cleared for topology-changing operations. This fixes incorrect
interpolation of the flag as noted in #104376. Generally it isn't
possible to interpolate it through topology-changing operations.
After this, only the seam status needs to be removed from edges before
we can replace them with the generic `int2` type (or something similar)
and reduce memory usage by 1/3.

In the future `BM_ELEM_DRAW` could be removed as well. Currently it is
used and aliased by other defines in some non-obvious ways though.

Straightforward port. I took the oportunity to remove some C vector
functions (ex: copy_v2_v2).
This makes some changes to DRWView to accomodate the alignement
requirements of the float4x4 type.
This implements two optimizations:
* If the duplication count is constant, the offsets array can be
filled directly in parallel.
* Otherwise, extracting the counts from the virtual array is parallelized.
But there is still a serial loop over all elements in the end to compute
the offsets.

This declaration change tells the evaluation system that the radius
field is evaluated on the input geometry. Which in turn means that
attributes referenced by the radius field should be propagated to
the geometry.
Versioning code in `do_versions_after_linking_260` inserted new group input
and output nodes. And (reasonably?) expected sockets to exist on those nodes.
However, `nodeAddStaticNode` did not initialize sockets on nodes with that use
`declare_dynamic` yet. This patch changes it so that `declare_dynamic` is used
in more places, which caused issues during file loading when node groups are
updated in somewhat arbitrary order (not in an order that is based on which
groups use which).

This patch adds support for compilation and execution of GLSL compute shaders. This, along with a few systematic changes and fixes, enable realtime compositor functionality with the Metal backend on macOS. A number of GLSL source modifications have been made to add the required level of type explicitness, allowing all compilations to succeed.
GLSL Compute shader compilation follows a similar path to Vertex/Fragment translation, with added support for shader atomics, shared memory blocks and barriers.
Texture flags have also been updated to ensure correct read/write specification for textures used within the compositor pipeline. GPU command submission changes have also been made in the high level path, when Metal is used, to address command buffer time-outs caused by certain expensive compute shaders.

The code removed here was intended to be an optimization that
avoids creating an additional node to join multiple attribute sets.
However, that optimization did not work, because it did not take
into account whether the single attribute set is required or not.
Allow to explicitly swap node links by pressing the alt-key while
reconnecting node links. This replaces the old auto-swapping based on
matching prefixes in socket names.
The new behavior works as follows:
* By default plugging links into already occupied (single input)
sockets will connect the dragged link and remove the existing one.
* Pressing the alt-key while dragging an existing node link from one
socket to another socket that is already connected will swap the
links' destinations.
* Pressing the alt-key while dragging a new node link into an already
linked socket will try to reconnect the existing links into another
socket of the same type and remove the links, if no matching socket
is found on the node. This is similar to the old auto-swapping.
Swapping links from or to multi input sockets is not supported.
This commit also makes the link drag tooltip better visible, when using
light themes by using the text theme color.

In the node groups for T103730, the "Points of Curve" node is often used to
retrieve the root point of every curve. Since the curve point offsets array
already contains that data directly, we can detect this as a special case and
avoid all the other work.

When the sort weights are a single value, they have no effect,
so sorting the relevant indices for the element will be wasted work.
The sorting is expensive compared to the rest of the node. In my
simple test of the points of curve node, it became 6 times faster
when the weights are a single value.
The list was populated from the base (unevaluated) object, but now that
Geometry nodes can generate various layers this is impractical..

`remember_deformed_curve_positions_if_necessary` has to be called before
topology changing operations on curves. Otherwise the crazy-space data
is invalid.
The call to BKE_volume_grid_openvdb_for_write() was accidentally removed
in D15806. This adds it to BKE_volume_grid_transform_matrix_set() to
avoid that it happens again when that function is used.

This improves performance in cases where the Set Position node is "turned off"
by passing `false` into the selection input.
It's possible that the node still takes some time in this case currently, because
it is destructing the input fields which may reference geometries that need
to be destructed as well. We could potentially change this node (and others)
so that the field inputs are only requested when the selection is not a
constant `false`.
This was not done originally, because one had to iterate over all curves
to get the number of points which had some overhead. Now the number
of points is stored all the time anyway.
The `fix_link_cycles` function added in rB2ffd08e95249df2a068dd did not
handle the case correctly when there are multiple cycles going through
the same socket.
This adds a new `Interpolate Curves` node. It allows generating new curves
between a set of existing guide curves. This is essential for procedural hair.
Usage:
- One has to provide a set of guide curves and a set of root positions for
the generated curves. New curves are created starting from these root
positions. The N closest guide curves are used for the interpolation.
- An additional up vector can be provided for every guide curve and
root position. This is typically a surface normal or nothing. This allows
generating child curves that are properly oriented based on the
surface orientation.
- Sometimes a point should only be interpolated using a subset of the
guides. This can be achieved using the `Guide Group ID` and
`Point Group ID` inputs. The curve generated at a specific point will
only take the guides with the same id into account. This allows e.g.
for hair parting.
- The `Max Neighbors` input limits how many guide curves are taken
into account for every interpolated curve.

Based on discussion about T102962, rename the "Face Set Boundaries" node
to "Face Group Boundaries" and the Accumulate Field node's "Group Index"
socket to "Group ID". This convention of "__ Group" and "Group ID" will
be used more in other nodes in the future.
This commit doesn't affect forwards or backwards compatibility.
The same logic from D17025 is used in other places in the curve code.
This patch uses the class for the evaluated point offsets and the Bezier
control point offsets. This helps to standardize the behavior and make
it easier to read.
Previously the Bezier control point offsets used a slightly different standard
where the first point was the first offset, just so they could have the same
size as the number of points. However two nodes used a helper function
to use the same `OffsetIndices` system, so switch to that there too.
That requires removing the subtraction by one to find the actual offset.
Also add const when accessing data arrays from curves, for consistency.

These warnings can reveal errors in logic, so quiet them by checking
if the features are enabled before using variables or by assigning
empty strings in some cases.
- Check CMAKE_THREAD_LIBS_INIT is set before use as CMake docs
note that this may be left unset if it's not needed.
- Remove BOOST/OPENVDB/VULKAN references when disable.
- Define INC_SYS even when empty.
- Remove PNG_INC from freetype (not defined anywhere).
There is a utility method on `CurvesGeometry` to build a map of the
curve for each point. Use that in two more places and make sure its
implementation is multithreaded, which gives a slight speedup
in a simple test file.
This abstraction is rarely used. It could be replaced by some more
general "query" API in the future. For now it's easier to just compare
pointers in the Set Position node where this was used.
This is possible now, because mesh positions are stored as flat `float3`
arrays (previously, they were stored as `MVert` with some other data
interleaved).
This changes how we access the points that correspond to each curve in a `CurvesGeometry`.
Previously, `CurvesGeometry::points_for_curve(int curve_index) -> IndexRange`
was called for every curve in many loops. Now one has to call
`CurvesGeometry::points_by_curve() -> OffsetIndices` before the
loop and use the returned value inside the loop.
While this is a little bit more verbose in general, it has some benefits:
* Better standardization of how "offset indices" are used. The new data
structure can be used independent of curves.
* Allows for better data oriented design. Generally, we want to retrieve
all the arrays we need for a loop first and then do the processing.
Accessing the old `CurvesGeometry::points_for_curve(...)` did not follow
that design because it hid the underlying offset array.
* Makes it easier to pass the offsets to a function without having to
pass the entire `CurvesGeometry`.
* Can improve performance in theory due to one less memory access
because `this` does not have to be dereferenced every time.
This likely doesn't have a noticable impact in practice.
