Texture usage flags can now be provided during texture creation specifying
the ways in which a texture can be used. This allows the GPU backends to
perform contextual optimizations which were not previously possible. This
includes enablement of hardware lossless compression which can result in
a 15%+ performance uplift for bandwidth-limited scenes on hardware such
as Apple-Silicon using Metal.
GPU_TEXTURE_USAGE_GENERAL can be used by default if usage is not known
ahead of time. Patch will also be relevant for the Vulkan backend.

Missed in the first commit[1].
Initially it was reported that the `flags` parameter was unused on
`imb_cache_filename` but it turns out another swath of code was unused
related to that same function. Clean this up now too.

This removes the unused code for the IBM tile cache APIs. These have
been unused for as far back as I could manage to search.
Since TIFF was used for the cached images, this removal will allow for
an easier review when it comes time to move TIFF to OIIO as part of
T101413.

Motivated by long loading times in T101969, reduces render preparation time from 14sec to 6sec.
Another possible improvement would be to use C++ and template based on OCIO vs. sRGB,
but moving the file to C++ seems nontrivial (and opens up the question whether ocio_capi
makes any sense then or we should just use OCIO directly) so I left it at a direct 1:1
parallelization of the existing code for now.

Currently, if an image exceed the texture limit setup by the user or the
GPU backend, it will be scaled down to satisfy the limit. However,
scaling happens independently per axis, that means the aspect ratio of
the image will not be maintained.
This patch corrects the smaller size to maintain the aspect ratio.

When the image colorspace is not data, linear or sRGB, the image will
be converted to float (and colorspace-converted) during loading.
However, if it also needs to be rescaled (due to exceeding the GPU
texture size limit), the resizing assumed that it's still a byte
texture.
These functions are almost identical, the main difference being
BLI_join_dirfile didn't trim existing slashes when joining paths
however this isn't an important difference that warrants a separate
function.
According to information I gathered, ffmpeg seeks internally using DTS
values instead of PTS. In some files DTS and PTS values are offset and
ffmpeg fails to seek correctly to keyframe located before requested PTS.
This issue become evident after hardcoded preseek of 25 frames was
removed and effort went into more precise seeking to improve
performance. It was thought, that this is bug in ffmpeg code, but
after reading some discussions, I don't think it is considered as such
by their developers, see below:
http://ffmpeg.org/pipermail/ffmpeg-devel/2018-March/226354.htmlhttps://trac.ffmpeg.org/ticket/1189
Best solution seems to be to add small preseek value possibly at
detriment of performance, so 3 frames of preseek are applied. Number 3
was chosen experimentally.
Performance impact seems to be insignificant with this change.

When image data exceeds half float ranges values are set to +/-
infinity that could lead to artifacts later on in the pipeline.
Color management for example.
This patch adds a utility function `IMB_gpu_clamp_half_float`
that clamps full float values to fit within the range of
half floats.
This fixes T98575 and T101601.
This is the conventional way of dealing with unused arguments in C++,
since it works on all compilers.
Regex find and replace: `UNUSED\((\w+)\)` -> `/*$1*/`
Match minimum supported versions from the WIKI [0] by raising them to:
- GCC 9.3.1
- CLANG 8.0
- MVCS 2019 (16.9.16 / 1928)
Details:
- Add CMake checks that ensure supported compiler versions early on.
- Previously GCC per-processor version checks served to exclude
`__clang__`, in some cases this has been replaced by explicitly
excluding `__clang__`. This was needed as CLANG treated some of these
flags differently to GCC, causing the build to fail.
- Remove USE_APPLE_OMP_FIX GCC-4.2 OpenMP workaround.
- Remove linking error workaround for old MSVC versions.

This is done by checking the number of bitplanes from the image buffer.
We assume that for float buffer to use the same bitplanes as it was a
byte buffer.
Then, the data of the image buffer is packed at the start of the `rect` or
`float_rect` before upload.

Note that not all grayscale textures have been stored as BW images so the
amount of memory that can be reduced would be more.
