Improvements to packing efficiency and updating UV packing API.
* Add #pack_islands_alpaca_rotate, the fast alpaca-style packer with rotation.
* Update heuristic for sorting islands based on longest edge.
(Improves pack efficiency when rotation is enabled.)
* Add `aspect_y` to UV Packing API, to support non-square materials in the future.

When all of the input meshes have no loose edges, the output won't have
any either, but finding that out for the output is much more expensive.
Copy this tag to the output mesh to save processing time when drawing.
In my test creating 1 million instances of a 16 face mesh, this changed
the time for the draw cache loose geometry extraction from 220 ms to
131 ms.
For now, only do this when the loose edges of the inputs are already
cached (primitive nodes, for example). This avoids paying the cost of
calculation when we don't know it will be necessary.
It doesn't take much time to know whether all of the curves have more
than a single point, and if that's the case, we know for sure there are
no loose edges in the mesh. This can save time when creating the mesh
draw cache. The time for finding loose geometry goes from 180 ms to
104 ms for a large molecular nodes test file.
For the single-threaded part of the curve to mesh conversion, avoid
writing to two logically separate arrays in the same loop. Instead
run the calculation on two separate threads if the output is large.
Timing for `calculate_result_offsets` when processing 1 million curves:
Before: Average: 10.4 ms, Min: 9.4 ms
After: Average: 9.2 ms, Min: 7.7 ms
Now that mesh primitive nodes calculate their bounds in constant time,
it's worth updating the bounds eagerly when translating a geometry
since doing so should be very cheap and might save a more significant
amount of time if they're needed later.
Also slightly unify the translation functions for the different types.

Previous code was using BKE_mesh_uv_vert_map_get_vert to somewhat
detect identical UV values on mesh vertices. But this was not
handling the case when separate mesh vertices still use the same UV
values (e.g. cube with all six faces mapped to whole image).
Replace usage of BKE_mesh_uv_vert_map_get_vert with a simple "unique UV
value" map, very similar to how OBJ normals are calculated for export.
Measurements on a somewhat extreme case: exporting "Rungholt" Minecraft
level from https://casual-effects.com/data time (Win10, Ryzen 5950X)
goes 2.9sec -> 2.2sec, and resulting file size 486MB -> 231MB. This
particular model has a lot of mesh faces mapping to the same places
in UV map.
On less extreme cases the timings are similar between old and new
code, with a tiny speedup in most tests I've tried.

"Rotate Normals" is a changeable operation like any other and does not
need to be hardcoded.
An advantage of exposing this modal is that the shortcut key now
appears in the header when rotating an edited mesh.
Avoid calling `restoreTransObjects`, `resetTransModal`,
`resetTransRestrictions` and `initSnapping` for each change.
Also bring `applyMouseInput` close to the rest of the code.
No functional changes.
The lack of organization in the values of the constants that indicate
the properties was prone to errors.
One error that can be noticed is that the values of
`P_ORIENT_AXIS_ORTHO` and `P_VIEW2D_EDGE_PAN` were the same.
(not really a problem though)
UV attribute refactor in 6c774feb has changed the logic from "UV data does not exist" to "there's no active UV layer". The repro mesh has a UV layer, but not UV data due to the mesh being only a point cloud.

The tooltip of the map range node in the compositing section was displaying that the output value was between 0.0 and 1.0 whereas it is between To Min and To Max value so I just changed the string.

IMath is required for building with vulkan. This patch adds
dependencies to shader_builder for now.
Currently there is a difference between windows and other OS's in
which variable the library is stored. Might be because imath isn't
a direct dependecy. As this is a compilation error I did the quickest
solution and check with platform module what would be the best solution.

Regression introduced at 19b63b932d
The crash happened in `gizmogroup_xform_find` because
`t->region->gizmo_map` was `nullptr`.
The `T_NO_GIZMO` flag was supposed to prevent the
`gizmogroup_xform_find` function from being called, but it was being
removed with `t->flag = t->flag & ~T_PROP_EDIT_ALL;`.
This is because 19b63b932d missed updating the maximum enum value in
`ENUM_OPERATORS`.
The fix is simply to set the correct maximum value in `ENUM_OPERATORS`.
But for more safety, `gizmogroup_xform_find` now returns early when the
region does not have `gizmo_map`.

Before this, when the animation is playing and the set of cached frames
changes the timeline is out-of-date which can be confusing.
Now the cached frames are redrawn whenever the current-frame indicator is
redrawn. This fixes the issue but also causes redraws when they are not necessary.
Currently, that does not seem to be an issue,

When using the Low or Medium settings on the Glare node, the generated
glare has an offset toward the lower left corner of the image. That's
because the shader erroneously has logic that assumes non-normalized
coordinates, so its offsets are in the pixel space of the original
image. To fix this, we just use a fixed 0.5 offset in the output pixel
space to evaluate at the center of pixels.
In the future, we might look into using a more advanced downsampling
scheme to avoid temporal instability, which is a new requirement due to
the viewport compositor.
Adding checks for platform capabilities involved adding functions
to multiple classes and was too involved.
Replace this with a single GHOST_System::getCapabilities() function.
This patch implements the Anti-Aliasing node by porting SMAA from
Workbench into a generic library that can be used by the realtime
compositor and potentially other users. SMAA was encapsulated in an
algorithm to prepare it for use by other nodes that require SMAA
support.

Vertex paint's filter operators were not properly going through the SculptSession API.
Undo didn't work; sometimes the operators would do nothing or produce corrupted colors.
The `transform_active_color` helper function now handles all of this. It ensures a valid
SculptSession exists and executes an undo push.

If the variable size option of the Blur node was previously set to true
and the type of blur was later set to Fast Gaussian, variable size blur
will take effect, even though the option is not visible to the user.
This patch fixes the issue by disabling variable size blur when the blur
type is set to Fast Gaussian.
It worked until now because `<iostream>` was included by other headers
before the rotation ones. But this didn't work in all cases. This commit
make sure all rotation type headers include it.
Effectively replicate the behavior of the function in the manner
which is used for autosave file.
There might be better a solution which is cross-platform and does
not suffer from the time of check, time of use (TOCTOU) vector of
attack. This seems to be a bigger project to figure out, so until
then silence the warning: it is fine since the directory is only
used to chdir to, so worst case an external attacker can introduce
is a test failure.
It provides path to a directory suitable for storing temporary files
which satisfies the following conditions:
- The directory exists.
- The return path has trailing directory separator.
It is based on the code used in the appdir.c to get the temporary
directory.
For the C++ people: this is similar to the temp_directory_path()
from the std::filesystem.
No functional changes expected as it is a new code which is planned
to be used on other places as a followup development.

the code would try to access `FCurve.bezt` without checking that exists.
When the curve is baked that is a null pointer.

Add a Gaussian smoothing operator to supersede the current
smoothing operator in the graph editor.
Advantage over the current implementation:
* Supports modal operations
* Is independent of key density
* More options in the redo panel
* More predictable Impulse Response
Option in the redo panel to change
Filter Width: How far out on each side of a key the code checks
to average key values
Sigma: The shape of the bell curve, lower values make a sharper bell curve
reducing the smoothing effect.
Too High values will make the code behave like an average filter as the
curve in the -1/1 range will almost be flat.
On a technical note, the operator needs to store additional data when running in modal
to avoid allocating/deallocating data on every modal run.
For that reason the `tGraphSliderOp` struct has been extended with
`void *operator_data` and `void (*free_operator_data)(void *operator_data)`.
The former is the data and the latter is a function responsible for freeing that data.
