Fix boundary error in `BLI_str_unescape_ex`. The `dst_maxncpy` parameter
indicates the maximum buffer size, not the maximum number of characters.
As these are strings, the loop has to stop one byte early to allow space
for the trailing zero byte.
Thanks @mano-wii for the patch!

The idea is to keep `is_any_zero` in the `blender::math` namespace,
so instead of trying to be clever, just move it there and expand the
function where it was used in the class.

Finding the greatest and/or smallest element in an array is a common
need. This commit refactors the point cloud bounds code added in
6d7dbdbb44f379682 to a more general header in blenlib.
This will allow reusing the algorithm for curves without duplicating it.

This is meant to complement the `blender::math` functions recently
added by D13791. It's sometimes desired to template an operation to work
on vector types, but also basic types like `float` and `int`. This patch
adds that ability with a new `BLI_math_base.hh` header.
The existing vector math header is changed to use the `vec_base` type
more explicitly, to allow the compiler's generic function overload resolution
to determine which implementation of each math function to use.
This is a relatively large change, but it also makes the file significantly
easier to understand by reducing the use of macros.

Error in a9f023e226389461b1140

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.

This implements the update cache described in T95401.
The cache is currently only used for drawing strokes and
sculpting (using the push brush).
**Note: Making use of the cache throughout grease pencil will
have to be done incrementally in other patches. **
The update cache stores what elements have changed in the
original data-block since the last time the eval object
was updated. Additionally, the update cache can store multiple
updates to the data and minimizes the number of elements
that need to be copied.
Elements can be tagged using `BKE_gpencil_tag_full_update` and
`BKE_gpencil_tag_light_update`. A full update means that the element
itself will be copied but also all of the content inside. E.g. when a
layer is tagged for a full update, the layer, all the frames inside the
layer and all the strokes inside the frames will be copied.
A light update means that only the properties of the element are copied
without any of the content. E.g. if a layer is tagged with a light
update, it will copy the layer name, opacity, transform, etc.
When the update cache is in use (e.g. elements have been tagged) then
the depsgraph will not trigger a copy-on-write, but an update-on-write.
This means that the update cache will be used to determine what elements
have changed and then only those elements will be copied over to the
eval object.
If the update cache is empty or the data block was tagged with a full
update, we always fall back to a copy-on-write.
Currently, the update cache is only used by the active depsgraph. This
is because we need to free the update cache after an update-on-write so
it's reset and we need to make sure it is not freed or read by other
depsgraphs.

This is almost always meaningless as most code has changed
since the comment was added. Besides this, version control can be used
to check if/when a file was modified.
Some cases of this were kept when they contain details

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).

Every translation unit that included the modified headers generated
some extra code, even though it was not used. This adds unnecessary
compile time overhead and is annoying when investigating the

Previously, these methods used the more generic substring-finding
algorithm, which is more complex and slower.
Using the more specialized methods results in a noticable speedup
in the obj importer (D13958).

Adding better support for drawing huge images in the image/uv editor. Also solved tearing artifacts.
The approach is that for each image/uv editor a screen space gpu texture is created that only contains
the visible pixels. When zooming or panning the gpu texture is rebuild.
Although the solution isn't memory intensive other parts of blender memory usage scales together with
the image size.
* Due to complexity we didn't implement partial updates when drawing images tiled (wrap repeat).
This could be added, but is complicated as a change in the source could mean many different
changes on the GPU texture. The work around for now is to tag all gpu textures to be dirty when
changes are detected.
Original plan was to have 4 screen space images to support panning without gpu texture creation.
For now we don't see the need to implement it as the solution is already fast. Especially when
GPU memory is shared with CPU ram.

Changes to recent addition: c85c52f2ce478ab0e30c5e93fd5a5cb812db232f.
Having both BLI_paths_equal and BLI_path_cmp made it ambiguous
which should be used, as `BLI_paths_equal` wasn't the equivalent to
`BLI_path_cmp(..) == 0` as it is for string equals macro `STREQ(..)`.
It's also a more specialized function which is not used for path
comparison throughout Blender's internal path handling logic.
Instead rename this `BLI_path_cmp_normalized` and return the result of
`BLI_path_cmp` to make it clear paths are modified before comparison.
Also add comments about the conventions for Blender's path comparison
as well as a possible equivalent to Python's `os.path.samefile`
for checking if two paths point to the same location on the file-system.

Add `USD Preview Surface From Nodes` export option, to convert a
Principled BSDF material node network to an approximate USD Preview
Surface shader representation. If this option is disabled, the original
material export behavior is maintained, where viewport setting are saved
to the Preview Surface shader.
Also added the following options for texture export.
- `Export Textures`: If converting Preview Surface, export textures
referenced by shader nodes to a 'textures' directory which is a
sibling of the USD file.
- `Overwrite Textures`: Allow overwriting existing texture files when
exporting textures (this option is off by default).
- `Relative Texture Paths`: Make texture asset paths relative to the
USD.
The entry point for the new functionality is
`create_usd_preview_surface_material()`, called from
`USDAbstractWriter::ensure_usd_material()`. The material conversion
currently handles a small subset of Blender shading nodes,
`BSDF_DIFFUSE`, `BSDF_PRINCIPLED`, `TEX_IMAGE` and `UVMAP`.
Texture export is handled by copying texture files from their original
location to a `textures` folder in the same directory as the USD.
In-memory and packed textures are saved directly to the textures folder.
This patch is based, in part, on code in Tangent Animation's USD
exporter branch.

This adds a new curve primitive to generate arcs.
Radius mode (default): Generates a fixed radius arc on XY plane
with controls for Angle, Sweep and Invert.
Points mode: Generates a three point curve arc from Start to End
via Middle with an Angle Offset and option to invert the arc.
There are also outputs for arc center, radius and normal direction
relative to the Z-axis.

This can simplify iterating through all of the indices in the vector,
which is fairly common, since one of the benefits of the data structure
is that all values are contiguous.
