Since USD is no longer statically linked these linker tricks
are no longer needed.

Pull Request #104627
When building a node group that's meant to be used directly in the
node editor as well as in the modifier, it's useful to be able to have
some inputs that are only meant for the node editor, like inputs that
only make sense when combined with other nodes.
In the future we might have the ability to only display certain assets
in the modifier and the node editor, but until then this simple solution
allows a bit more customization.

During hair grooming in curves sculpt mode, it is very useful when hair strands
are prevented from intersecting with the surface mesh. Unfortunately, it also
decreases performance significantly so we don't want it to be turned on all the time.
The surface collision is used by the Comb, Pinch and Puff brushes currently.
It can be turned on or off on a per-geometry basis.
The intersection prevention quality of this patch is not perfect yet. This can
be improved over time using a better solver. Overall, perfect collision detection
at the cost of bad performance is not necessary for interactive sculpting,
because the user can fix small mistakes very quickly. Nevertheless, the quality
can probably still be improved significantly without too big slow-downs depending
on the use case. This can be done separately from this patch.
Pull Request #104469
Previously, the node used the "true" normal of every looptri. Now it uses the
"loop normals" which includes e.g. smooth faces and custom normals. The true
normal can still be used on the points by capturing it before the Distribute node.
We do intend to expose the smooth normals separately in geometry nodes as well,
but this is an important first step.
It's also necessary to generate child hair between guide hair strands that don't
have visible artifacts at face boundaries.
For perfect backward compatibility, the node still has a "Legacy Normal" option
in the side bar. Creating the exact same behavior with existing nodes isn't
really possible unfortunately because of the specifics of how the Distribute
node used to compute the normals using looptris.

CustomData layer names should not be written except via the CusomData
api. Therefore use const char * instead of char * when referencing the
layer name.
Pull Request #104585
Avoid computing the non-derivative height twice.
The height is now computed as part of the main function, while the height at x and y offsets are still computed on a separate function.
The differentials are now computed directly at node_bump.

This adds a `select_lasso` and a `select_circle` function for the Curves object. It is used in the `view3d_lasso_select` and `view3d_circle_select` operator.

This adds a new `select_linked` function that selects all the points
on a curve if there is at least one point already selected.
This also adds a keymap for the operator.

Add `contains_group` method in python api for `NodeTree` type, cleanup
`ntreeHasTree` function, reuse `ntreeHasTree` in more place in code.
The algorithm has been changed to not recheck trees by using set.
Performance gains from avoiding already checked node trees:
Based on tests, can say that for large files with a huge number
of trees, the response speed of opening the search menu in the
node editor increased by ~200 times (for really large projects
with 16 individual groups in 6 levels of nesting). Group insert
operations are also accelerated, but this is different in some cases.

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.

Using callback functions didn't scale well as more arguments are added.
It got very confusing when to pass tehmarguments weren't always used.
Instead use a `FunctionRef` with indices for arguments. Also remove
unused edge arguments to topology mapping functions.
Adds an experimental option under "New Features" in preferences,
which enables visibility of the new Volume Nodes.
Right now this option does nothing but will be used during development.
See #103248
Pull Request #104552
Because of T95965, some attributes are stored as generic attributes
in Mesh but have special handling for the conversion to BMesh.
Expose a function to tell whether certain attribute names are handled
specially in the conversion, and refactor the error checking process
to use it. Also check for generic attributes on the face domain which
wasn't done before.

Pull Request #104567
When merging two gpencil layers, if the destination layer had a keyframe
where the source layer did not, strokes of the previous keyframe
in source layer were lost in that frame.
This happened because the merge operator was looping through
frames of the source layer and appending strokes in the
corresponding destination layer, but never completing
other frames than the ones existing in the source layer.
This patch fixes it by first adding in source layer
all frames that are in destination layer.

When the sequencer is empty (i.e., there are no sequences),
we would have the deselect_all variable set to true called
ED_sequencer_deselect_all to select any existing sequences.

Box-Selecting channels in the dope sheet with click-drag was no longer possible as of Blender 3.2
Due to the removal of tweak events the box select operator was always shadowed by the click operator.
Original Phabricator discussion here: https://archive.blender.org/developer/D17065
Use `WM_operator_flag_only_pass_through_on_press` on click operator to fix it

Without this, every access to "language" would warn that the enum
value didn't match a value in the enum items.
This made the bl_rna_manual_reference.py test output practically
unusable.
Documented all functions, adding use case and side effects.
Also replace the use of shortened argument name by more meaningful ones.
Renamed `GPU_batch_instbuf_add_ex` and `GPU_batch_vertbuf_add_ex` to remove
the `ex` suffix as they are the main version used (removed the few usage
of the other version).
Renamed `GPU_batch_draw_instanced` to `GPU_batch_draw_instance_range` and
make it consistent with `GPU_batch_draw_range`.
When nodes are copied to the clipboard, they don't need their declaration.
For nodes with dynamic declaration that might depend on the node tree itself,
the declaration could not be build anyway, because the node-clipboard does
not have a node tree.
Pull Request #104432
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.
Pull Request #104428
Currently there's no way to assign a geometry node group from the asset
browser to an object as a modifier without first appending/linking it
manually. This patch adds a drag and drop operator that adds a new
modifier and assigns the dragged tree.
Pull Request #104430
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.

Pull Request #104411
`bAnimContext` had a float property called `yscale_fac` that was used to define the height of the keyframe channels.
However the property was never set, only read so there really is no need to have it in the struct.
Moreover it complicated getting the channel height because `bAnimContext` had to be passed in.
Speaking of getting the channel height. This was done with macros. I ripped them all out and replaced them with function calls.
Originally it was introduced in this patch: https://developer.blender.org/rB095c8dbe6919857ea322b213a1e240161cd7c843

Blender was reporting that the GPU_TEXTURE_USAGE_HOST_READ wasn't set.
This is used to indicate that the textures needs to be read back to
CPU. Textures that don't need to be read back can be optimized by the
GPU backend.
