When sampling ImBuf can be a char or a float buffer. Current sampling
functions added overhead by checking which kind of buffer was passed
every pixel that was sampled. When performing image processing this
check can be removed outside the inner loop adding 5% of performance
increase in the `IMB_transform` operator.
Inside the sequencer the cropping and transform of images/buffers were
implemented locally. This reduced the optimizations that a compiler
could do and added confusing code styles. This patch adds
`IMB_transform` to reduce the confusion and increases compiler
optimizations as more code can be inlined and we can keep track of
indices inside the inner loop.
This increases end-user performance by 30% when playing back aa video
in VSE.

This patch changes occurrences of percentage to factor.
There are some usages of percentage left in there on purpose.
They are distinguished as follows:
- factor is 0-1 float
- percentage is 0-100 int

When using non-default system separator in filename path, code would end up
with an absolute path mixing regular and alternative separator,
confusing the rest of the path manipulations later on.
So this commit add proper replacements of alternative separators, and
path normalization.
Splitting out thread safe iteration logic means regular iteration
isn't checking for the thread-safe pointer each step.
This gives a small but measurable overall performance gain of 2-3%
when redrawing a high-poly mesh.

This change was prompted by D6408 which moves thumbnail extraction into
a shared function that happens use these endian defines but only links
blenlib.
There is no need for these defines to be associated with globals
so move into their own header.
Allows to define properties which will have proper units displayed
in the interface. The internal storage is expected to be seconds
(which matches how other times are stored in Blender).
Is not immediately used in Blender, but is required for the upcoming
feature in Cycles X (D11526)
The naming does not sound very exciting, but can't think of anything
better either.
For test it probably easiest to define FloatProperty with subdtype
of TIME_ABSOLUTE.

Previously, a vertex from destination mesh would always be added to all
transferred vgroup (with a 0.0 weight), even if none of its matching
sources in source mesh belonged to the matching source vgroups.
Now a destination vertex is only added to a given destination vgroup if
at least one of its source vertices belong to the matching source
vgroup.
Issue found and initial investigation by @pls in D11524, thanks!
TBBmalloc_proxy already takes care of any allocations
being done from MSVC compiled code, some of the dependencies
like GMP cannot be build with MSVC and we have to use
mingw to build them. mingw however links against the older
msvcrt.dll for its allocation needs, which TBBMallocProxy
does not hook.
GMP has an option to supply your own allocation functions
so we can still manually redirect them to TBBMalloc.
In a test-file with a boolean geometry node, this patch
uses 32s effective CPU time compared to 52s before.

To draw the overlay stats in columns the strings must be measured to
find the longest one. In some circumstances this measurement can be
incorrect. We draw the text with a specific size yet do not explicitly
set the size before calling BLF_size. This patch properly sets the size
so that the measurement will match what will be used for output.
See T88799 for examples of measurement failure.

First, expand on the interpolation to evaluated points with a templated
helper function, and a function that takes a GSPan. Next, add a set of
functions to `Spline` for interpolating at arbitrary intervals between
the evaluated points. The code for doing that isn't that complicated
anyway, but it's nice to avoid repeating, and it might make it easier
to unroll the special cases for the first and last points if we require
the index factors to be sorted.
This commit adds a node to output the convex hull of any input geometry
as a mesh, which is an enclosing geometry around a set of points.
All geometry types are supported, besides volumes.
The code supports operating on instances to avoid copying all input
geometry before the operation. The implementation uses the same backend
as the operation in edit mode, but uses Mesh directly instead of BMesh.
Attribute transfer is not supported currently, but would be a point of
improvement for the future if it can work in a predictable way on
different geometry input types.

Note that these changes are limited simple cases as these kinds of
changes could allow for errors when refactoring code when the known
state is not so obvious.
Use BM_iter_parallel for face tessellation, this gives around
6.5x speedup for BM_mesh_calc_tessellation on high poly meshes in my
tests, although exact speedup depends on available cores.
Support thread local storage for BLI_task_parallel_mempool,
as well as support for the reduce and free callbacks.
mempool_iter_threadsafe_* functions have been moved into a private
header thats only shared between task_iterator.c and BLI_mempool.c
so the TLS can be made part of the iterator array without having to
rely on passing in struct offsets.
Add test task.MempoolIterTLS that ensures reduce and free
are working as expected.

While this should not be allowed in general, there are some cases
(library overrides at least) where supporting this is mandatory.
Further more, comment stating that this could crash is from 2011, could
not reproduce any issue with current code. Commit comment was referring
to undo/redo, but in use cases here those should not affect things.
Note that in general, such relatively high-level checks should be
handled by high-level, close to user code (like in ED area e.g.), not in
low-level BKE code anyway.
