owner_id pointer.
Also rename the callback. That way, we can keep moving toward a more
generic handling of those embedded IDs (think e.g. about copy code).

Previously, curves sculpt tools only worked on original data. This was
very limiting, because one could effectively only sculpt the curves when
all procedural effects were turned off. This patch adds support for curves
sculpting while looking the result of procedural effects (like deformation
based on the surface mesh). This functionality is also known as "crazy space"
support in Blender.
For more details see D15407.

These mutable pointers present problems with ownership in relation to
proper copy-on-write for attributes. The simplest solution is to just
remove them and retrieve the layers from `CustomData` when they are
needed. This also removes the complexity and redundancy of having to
update the pointers as the curves change. A similar change will apply
to meshes and point clouds.
One downside of this change is that it makes random access with RNA
slower. However, it's simple to just use the RNA attribute API instead,
which is unaffected. In this patch I updated Cycles to do that. With
the future attribute CoW changes, this generic approach makes sense
because Cycles can just request ownership of the existing arrays.

Previously, things like materials, symmetry, and selection options
stored on `Curves` weren't copied to the result in nodes like the
subdivide and resample nodes. Now they are, which fixes some
unexpected behavior and allows visualization of the sculpt mode
selection.
In the realize instances and join nodes the behavior is the same as
for meshes, the parameters are taken from the first (top) input.
I also refactored some functions to return a `CurvesGeometry` by-value,
which makes it the responsibility of the node to copy the parameters.
That should make the algorithms more reusable in other situations.

This utility struct is useful outside of sculpting code as well.
|
|
This mirrors the C++ attribute API better, separates the implementation
of attributes from CustomData slightly, and makes functions simpler,
clearer, and safer.
Also fix an issue with removing an attribute caused by 97712b018df71c
meant the first attribute with the given type was removed instead of
the attribute with the given name.

The fix is to unify with the name we had for the old Curves objects.
That means that we will see them bothi (old and new curves) in the outliner
(under two different categories but with different names).
This is considered to be a temporary solution until we remove the old
curve system entirely.

In the latest discussions about curves/hair mesh attachement
information (T95776), it was decided to use UV coordinates to
store where on the mesh each root is. For that, we have to specify
which of the UV map attributes to use for UV lookups.
This property isn't used yet, but it will be shortly when refactoring
the attachement information in the add brush and the to particle
system conversion.

Previously the function had a fair amount of ugly boilerplate to avoid
allocating the temporary layers array, and then free it if necessary.
`blender::Vector` solves that problem more elegantly. Passing a span,
using references in a few cases, and using a switch statement also make
the functions simpler.
This refactoring is in preparation for D14583 and D14685.

This commit moves the code for the resample curves node to the geometry
module, to allow reusing it in any editor. Split from D14870.

Remembering the number of curves of every type makes it fast to know
whether processing specific to a single curve type has to be done.
This information was accessed in quite a few places, so this should be
an overall reduction in overhead for the new curves type.
The cache is computed eagerly, in other words every time after changing
the curve types. In order to reduce verbosity I added helper functions
for some common ways to set the types.

* Curves objects now support the geometry nodes modifier.
* It's possible to use the curves object with the Object Info node.
* The spreadsheet shows the curve data.
The main thing holding this back currently is that the drawing code
for the curves object is very incomplete. E.g. it resamples the curves
always in the end, which is not expected for curves in general.

Add "for_write" on function names that retrieve mutable data arrays.
Though this makes function names longer, it's likely worth it because
it allows more easily using the const functions in a non-const context,
and reduces cases of mistakenly retrieving with edit access.
In the long term, this situation might change more if we implement
attributes storage that is accessible directly on `CurvesGeometry`
without duplicating the attribute API on geometry components,
which is currently the rough plan.

A follow-up to e253f9f66d6f. Follow the policy from T85728
completely (using "num" as a prefix) and rename another function.
|
|
Rename "size" variables and functions to use "num" instead,
based on T85728 (though this doesn't apply to simple C++
containers, it applies here). Rename "range" to "points" in
some functions, so be more specific.

Create `Curves` directly, instead of using the conversion from
`CurveEval`. This means that the `tilt` and `radius` attributes
don't need to be allocated. The old behavior is kept by using the
right defaults in the conversion to `CurveEval` later on.
The Bezier segment primitive isn't ported yet, because functions
to provide easy access to built-in attributes used for Bezier curves
haven't been added yet.

Currently, any time a Curves data-block is created, the `curves_random`
function runs, filling it with 500 random curves, also adding a radius
attribute. This is just left over from the prototype in the initial
commit that added the type.
This commit moves the code that creates the random data to the curve
editors module, like the other primitives are organized.

The general idea here is to wrap the `CurvesGeometry` DNA struct
with a C++ class that can do most of the heavy lifting for the curve
geometry. Using a C++ class allows easier ways to group methods, easier
const correctness, and code that's more readable and faster to write.
This way, it works much more like a version of `CurveEval` that uses
more efficient attribute storage.
This commit adds the structure of some yet-to-be-implemented code,
the largest thing being mutexes and vectors meant to hold lazily
calculated evaluated positions, tangents, and normals. That part might
change slightly, but it's helpful to be able to see the direction this
commit is aiming in. In particular, the inherently single-threaded
accumulated lengths and Bezier evaluated point offsets might be cached.

This patch reverses the dependency between `BLI_math_vec_types.hh` and
`BLI_math_vector.hh`. Now the higher level `blender::math` functions
depend on the header that defines the types they work with, rather than
the other way around.
The initial goal was to allow defining an `enable_if` in the types header
and using it in the math header. But I also think this operations to types
dependency is more natural anyway.
This required changing the includes some files used from the type
header to the math implementation header. I took that change a bit
further removing the C vector math header from the C++ header;
I think that helps to make the transition between the two systems
clearer.

Use a shorter/simpler license convention, stops the header taking so
much space.

Based on discussions from T95355 and T94193, the plan is to use
the name "Curves" to describe the data-block container for multiple
curves. Eventually this will replace the existing "Curve" data-block.
However, it will be a while before the curve data-block can be replaced
so in order to distinguish the two curve types in the UI, "Hair Curves"
will be used, but eventually changed back to "Curves".
This patch renames "hair-related" files, functions, types, and variable
names to this convention. A deep rename is preferred to keep code
consistent and to avoid any "hair" terminology from leaking, since the
new data-block is meant for all curve types, not just hair use cases.
The downside of this naming is that the difference between "Curve"
and "Curves" has become important. That was considered during
design discussons and deemed acceptable, especially given the
non-permanent nature of the somewhat common conflict.
Some points of interest:
- All DNA compatibility is lost, just like rBf59767ff9729.
- I renamed `ID_HA` to `ID_CV` so there is no complete mismatch.
- `hair_curves` is used where necessary to distinguish from the
existing "curves" plural.
- I didn't rename any of the cycles/rendering code function names,
since that is also used by the old hair particle system.
