Only fixes compilation error, the functionality will be limited.
Currently we don't care that much, since all the work is done in
the branch anyway.
Later on when we'll know which fixes we need to apply on top of
latest OpenSubdiv library we will call a library upgrade.
Main goal is to make API simpler to follow (at least ion terms what
is defined/declared where, as opposite of handful big headers which
includes all the declarations), and also avoid a big set of long and
obscure functions.
Now C-API files are split into smaller ones, following OpenSubdiv
behavior more closely, and also function pointers in structures
used a lot more, which shortens functions names,
UV integration part in GL Mesh is mainly stripped away, it needs
to be done differently. On a related topic, UV coordinates API in
converter needs to be removed as well, we do not need coordinates,
only island connectivity information there.
Additional changes:
- Varying interpolation in evaluator API are temporarily disabled,
need to extend API somewhere (probably, evaluator's API) to inform
layout information of vertex data (whether it contains varying
data, width, stride and such).
- Evaluator now can interpolate face-varying data.
Only works for adaptive refiner, since some issues in OpenSubdiv
itself.
Planned changes:
- Remove uv coordinates from TopologyConverter.
- Support evaluation of patches (as opposite to individual coordinates
as it happens currently).
- Support more flexible layout of varying and face-varying data.
It is stupid to assume varying is 3 floats and face-varying 2 floats.
- Support of second order derivatives.
- Everything else what i'm missing in this list.
Features to get the 2nd, 3rd, 4th closest point instead of the closest, and
various distance metrics. No viewport/Eevee support yet.

This works for Cycles, Eevee, texture nodes and compositing. It helps to
reduce the number of math nodes required in various node setups.

- Logical use of fields since they define type information.
- Avoids using ordered-dict metaclass.
Properties using regular assignments will print a warning and load,
however the order is undefined.
- Made OpenSubdiv_GLMesh private
Previously, it was still accessible via C-API from C++ code.
- Don't implicitly refine evaluator when updating coarse positions,
now there is an explicit call to do this.
Allows to first apply all changes to the coarse mesh and then
refine once.
- Added coarse positions update from a continuous buffer with given
starts offset and stride.
Allows to update coarse positions directly from MVert array.
- Refiner is no longer freed when CPU evaluator is created.
Allows to re-use refiner for multiple purposes.
This is no longer needed with the new offscreen draw method, so use whatever
is default and hopefully fastest. Fixes console warnings in some setups that
don't have swap copy.
The X resource database is to be explicitly destroyed. This fixes 46 bytes
leak per every window DPI query (which happens a lot on window move/resize
and even on areas resize).
Unfortunately, this does not fully fix the leak since the known leak:
https://bugs.freedesktop.org/show_bug.cgi?id=94604
There were a number of cases where immActivate() and immDeactivate() could
get out of sync, causing crashes due to using a freed mutex lock. Refactor
the code now to hopefully avoid this always.
This makes it possible to have a single shading nodetree that contains
separate Cycles and Eevee shaders. By default the target is set to All
so shaders are shared.
Textures in 16 bit integer format are sometimes used for displacement, bump and normal maps and can be exported by tools like Substance Painter. Without this patch, Cycles would promote those textures to single precision floating point, causing them to take up twice as much memory as needed.

This deduplicates the calls for tile (un)mapping and allows to have a target buffer that is different from the source buffer (needed for baking and animation denoising).
