Previously, objects and geometries were mapped between frames
using different hash tables in a way that is incompatible with
geometry instances. That is because the geometry mapping happened
without looking at the `persistent_id` of instances, which is not possible
anymore. Now, there is just one mapping that identifies the same
object at multiple points in time.
There are also two new caches for duplicated vbos and textures used for
motion blur. This data has to be duplicated, otherwise it would be freed
when another time step is evaluated. This caching existed before, but is
now a bit more explicit and works for geometry instances as well.

Althought the float buffers are only used as cache, current code paths
don't look at the flags to identify which kind of image it is. Actual
fix would be to check flags, but that wouldn't be something to add one
week before release.
This commit fixes it by removing the buffers after use in the image
engine.
This commit renames enums related the "Curve" object type and ID type
to add `_LEGACY` to the end. The idea is to make our aspirations clearer
in the code and to avoid ambiguities between `CURVE` and `CURVES`.
Ref T95355
To summarize for the record, the plans are:
- In the short/medium term, replace the `Curve` object data type with
`Curves`
- In the longer term (no immediate plans), use a proper data block for
3D text and surfaces.

This adds initial support for edit mode for the experimental new curves
object. For now we can only toggle in and out of the mode, no real
interraction is possible.
This patch also adds empty menus in edit mode. Those were added mainly
to quiet warnings as the menus are programmatically added to the edit
mode based on the object type and context.

This adds the boilerplate code that is necessary to use the tool/brush/paint
systems in the new sculpt curves mode.
Two temporary dummy tools are part of this patch. They do nothing and
only serve to test the boilerplate. When the first actual tool is added,
those dummy tools will be removed.

Previous implementation had a copy of the image user, which doesn't
contain all the data to identify changes. This patch introduces a new
struct to store the data and can be extended with other data as well
(color spaces, alpha settings).
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.

Not all coarse vertices were used to compute the center value (off by
one), and the interpolation for the current would always start at the
base corner for the base face instead of the base corner for the current
patch.
The issue has two causes: on one hand origin indices were not handled
properly, on the other hand the extraction type (Mesh, BMesh, or mapped)
was not detected correctly.
For the second case reuse the MeshRenderData creation from the coarse
code path so that we make the same decisions. Loose geometry extraction
had to be updated to properly handle the BMesh cases.
For the origin indices, in some cases (for edges and faces), the arrays
used by the subdivision code already have the origin indices baked into
them, so mapping them a second time through the origin index layer is
wrong, and could cause out of bounds accesses.
For vertices especially, we would use two arrays: one for mapping
subdivision vertices to coarse vertices, and another one to map coarse
vertices to subdivision loops used for the selection index buffer. The
second one is now removed (which saves a bit of memory) as it is did not
have the proper data setup for use with the origin indices and we can
easily compute it using the first array anyway.
Currently one a single texture slot is used to update the screen.
Current design is implemented to use multiple textures.
for now limit the number of texture slots to 1.
Due to the freeing and re-creation of textures performed when binding
offscreen viewports, VR viewport textures would be needlessly
re-created every drawing iteration, leading to a negative impact on VR
frame rate.
This was brought to light by 6738ecb64e, which introduced an
additional texture clear operation on initialization and was
prohibitively costly on some systems when performed every frame.
Now, the textures for VR viewports will not be always re-created
during offscreen binding, but only when necessary using a pre-drawing
step (`wm_xr_session_surface_offscreen_ensure()`).

The crash was happening when the mesh had loose edges.
Loose edges are not part of OpenSubdiv topology and hence should not be
communicated to the refiner. Pass ta boolean flag indicating whether an
edge is loose or not in the mesh foreach routines, which seems to be
the easiest way.
Viewport cull bones during selection to avoid depth-picking
reading the depth buffer for bones that aren't in the viewport.
Files with thousands of bones could hang blender for seconds while
selecting. The issue could still happen with overlapping bones or when
zoomed out so all bones are under the cursor, however in practice this
rarely happens.
Now files with many bones select quickly.
Related changes include:
- Split `BKE_pchan_minmax` out of `BKE_pose_minmax`.
- Add `mat3_to_size_max_axis` to return the length of the largest
axis (used for scaling the radius).

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.

Dashed line display was changed since 2.7x, using white on black
instead of grey on black.
This made selection difficult to see as white is brighter
than the default selected color.
Match the grey used in 2.7x.
