openSubdiv_init() would detect available evaluators before any OpenGL context
exists, causing a crash with libepoxy. This test however is redundant as we
already check the requirements on the Blender side through the GPU API.
To simplify things, completely remove the device detection in the opensubdiv
module and reduce the evaluators to just CPU and GPU. The plan here is to move
to the GPU module abstraction over OpenGL/Metal/Vulkan and so all these
different backends no longer make sense.
This also removes the user preference for OpenSubdiv compute device, which was
not used for the new GPU subdivision implementation.

This evaluator is used in order to evaluate subdivision at render time, allowing for
faster renders of meshes with a subdivision surface modifier placed at the last
position in the modifier list.
When evaluating the subsurf modifier, we detect whether we can delegate evaluation
to the draw code. If so, the subdivision is first evaluated on the GPU using our own
custom evaluator (only the coarse data needs to be initially sent to the GPU), then,
buffers for the final `MeshBufferCache` are filled on the GPU using a set of
compute shaders. However, some buffers are still filled on the CPU side, if doing so
on the GPU is impractical (e.g. the line adjacency buffer used for x-ray, whose
logic is hardly GPU compatible).
This is done at the mesh buffer extraction level so that the result can be readily used
in the various OpenGL engines, without having to write custom geometry or tesselation
shaders.
We use our own subdivision evaluation shaders, instead of OpenSubDiv's vanilla one, in
order to control the data layout, and interpolation. For example, we store vertex colors
as compressed 16-bit integers, while OpenSubDiv's default evaluator only work for float
types.
In order to still access the modified geometry on the CPU side, for use in modifiers
or transform operators, a dedicated wrapper type is added `MESH_WRAPPER_TYPE_SUBD`.
Subdivision will be lazily evaluated via `BKE_object_get_evaluated_mesh` which will
create such a wrapper if possible. If the final subdivision surface is not needed on
the CPU side, `BKE_object_get_evaluated_mesh_no_subsurf` should be used.
Enabling or disabling GPU subdivision can be done through the user preferences (under
Viewport -> Subdivision).

We have established a convention of exposing the most important
settings from popovers, then aligning a popover to control more
detailed settings.
The file browser has powerful display / filtering settings, but
they're hidden in popovers at the moment, so it's sometimes a pain
to use them. The "display as" options are now exposed to the left of
the display settings popover, and the "filter" toggle is exposed to
the left of the filter settings popover. This convention is familiar
and intuitive for users and makes interaction faster.
Note that the "show hidden" item in the filter popover still has an
effect if filtering is disabled.
This commit also:
- Removes the icons in the "Sort By" enum
- Uses property split for the "Sort By" enum
- Very slightly increases the default width of the file browser

and releases under development use "2.90.0 Alpha", "2.90.0 Beta".
Some Python add-ons may need to lower the Blender version in bl_info to

This patch implements dumping images from cache to HDD.
The main goal of this system is to provide a means to achieve consistent playback speed mainly for strips that are not possible to preview in real time.
How to use:
Disk cache has own settings in user preferences for path to storage, size limit and compression level.
To use disk cache, you need to check `Use Disk Cache` box, set `Disk Cache Directory`, `Disk Cache Limit` and save or open existing .blend file.
By default sequencer output will be cached only. Manual setting is possible in cache panel.
Uses:
- Replacement or alternative for proxies. Disk cache will work with any strip type, supports float images as well.
- Storage for strip thumbnails.
- Less RAM needs to be allocated for preview cache
How it works:
Disk cache is extension of RAM cache. Every image, that is stored or deleted in RAM will be stored or deleted on HDD as well. Images can be compressed to save space and for use on slower drives. Compressed images are slower to write and read though.
Images are stored in bulk of 100 rendered frames per one file. This is to overcome slow file access time for large amount of files. Drawback is, that if one frame needs to be redrawn, all 100 frames are deleted.

This adds the ID-Filters visible on append/link to the settings the file
browser remembers, potentially storing them in the Preferences.
Artists in the studio here requested this. They typically have to set up
the same or similar settings every time, so this saves them from that.
The default was changed with an initial implementation of the feature.
With the feedback from animators, having a behavior which affects curves
outside of a changing range is not convenient for professional animators
working on high quality character animation. On the other hand, automatic
smoothing is better for casual animation of object motion.

This makes it so that some display related properties of the file
browser state are remembered in the Preferences. Otherwise, users often
end up doing the same set up work over and over again, so this is a
nice way to save users some work.
It's typical for other file browsers to remember their state too, so
another benefit is having a more conventional behavior, meeting user
expectations better.
Some points:
* We currently store: Window size, display type, thumbnail size,
enabled details-columns, sort options, "Show Hidden" option. More can
be added easily.
* No changes are stored to the Preferences if "Auto-save Preferences"
is disabled. This is how Quick Favorites behave too and it's a
reasonable way to make this behavior optional.
* The Preferences are only saved to permanent memory upon closing
Blender, following existing convention of Preferences and Quick
Favorites.
* If settings weren't actually changed, Preference saving is skipped.
* Only temporary file browsers save their state (invoked through
actions like open or save), not regular file browser editors. These
are usually used for different purposes and workflows.
* Removes "Show Thumbnails" Preferences option. It would need some
special handling, possibly introducing bugs. For users, this
simplifies behavior and should make things more predictable.

Turntable and trackball have different settings because
turn-table uses an angle-per-pixel, where as trackball
values are relative to the view-port size so a scale is used.
The sensitivity is scaled by the pixel size so hi-dpi views don't rotate faster.
Simplify preferences by removing the ability to load them from
either the startup.blend or userpref.blend.
Also simplifies updating default preferences by moving
them to a struct definition.
