This has some advantages over operator search:
- Some operators need options set to be usefully accessed.
- Shows key bindings to access menus
(for actions that don't have key bindings themselves).
- Non operator actions such as check-boxes are also shown.
- Menu items can control execution context, using invoke or execute
where appropriate so we can control how the operator runs.

This patch adds ability to set up colors and size of background
(transparency) checkerboard pattern in viewport and 2d editors. No new
backgrounds, only changing colors in existing ones.
This is not the background of the viewport, it is a transparency
checkerboard that is turned on only in render mode, when the
transparency mode is on. And also in 2D-editors, (image, sequencer,

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.

The feature is hidden behind an experimental option, you'll have to
enable it in the preferences to try it.
This feature is not yet considered fully stable, crashes may happen, as
well as .blend file corruptions (very unlikely, but still possible).
In a nutshell, the ideas behind this code are to:
* Detect unchanged IDs across an undo step.
* Reuse as much as possible existing IDs memory, even when its content
did change.
* Re-use existing depsgraphs instead of building new ones from scratch.
* Store accumulated recalc flags, to avoid needless re-compute of things
that did not change, when the ID itself is detected as modified.
See T60695 and D6580 for more technical details.

Blender supports locking vertex groups to prevent changes to the

There were two reasons the USD Exporter was listed as experimental:
- Originally there was no deduplication of mesh normals & UV coordinates
(resolved in rBf5e00f735106b5ec635806a4c795a2bc46ae8369), and
- the way materials were exported was incompatible with instancing with
USD 19.07. This seems to be resolved with the current version of USD
(19.11).
Blender (more specifically, `makesdna`) doesn't seem to like empty DNA
structs, so I couldn't remove all properties from
`UserDef_Experimental`. Instead I have just kept `char _pad0[8]`.

- The USD libraries are built by `make deps`, but not yet built by
install_deps.sh.
- Only experimental support for instancing; by default all duplicated
objects are made real in the USD file. This is fine for exporting a
linked-in posed character, not so much for thousands of pebbles etc.
- The way materials and UV coordinates and Normals are exported is going
to change soon.
- This patch contains LazyDodo's fixes for building on Windows in D5359.
== Meshes ==
USD seems to support neither per-material nor per-face-group
double-sidedness, so we just use the flag from the first non-empty
material slot. If there is no material we default to double-sidedness.
Each UV map is stored on the mesh in a separate primvar. Materials can
refer to these UV maps, but this is not yet exported by Blender. The
primvar name is the same as the UV Map name. This is to allow the
standard name "st" for texture coordinates by naming the UV Map as such,
without having to guess which UV Map is the "standard" one.
Face-varying mesh normals are written to USD. When the mesh has custom
loop normals those are written. Otherwise the poly flag `ME_SMOOTH` is
inspected to determine the normals.
The UV maps and mesh normals take up a significant amount of space, so
exporting them is optional. They're still enabled by default, though.
For comparison: a shot of Spring (03_035_A) is 1.2 GiB when exported
with UVs and normals, and 262 MiB without. We probably have room for
optimisation of written UVs and normals.
The mesh subdivision scheme isn't using the default value 'Catmull
Clark', but uses 'None', indicating we're exporting a polygonal mesh.
This is necessary for USD to understand our normals; otherwise the mesh
is always rendered smooth. In the future we may want to expose this
choice of subdivision scheme to the user, or auto-detect it when we
actually support exporting pre-subdivision meshes.
A possible optimisation could be to inspect whether all polygons are
smooth or flat, and mark the USD mesh as such. This can be added when
needed.
== Animation ==
Mesh and transform animation are now written when passing
`animation=True` to the export operator. There is no inspection of
whether an object is actually animated or not; USD can handle
deduplication of static values for us.
The administration of which timecode to use for the export is left to
the file-format-specific concrete subclasses of
`AbstractHierarchyIterator`; the abstract iterator itself doesn't know
anything about the passage of time. This will allow subclasses for the
frame-based USD format and time-based Alembic format.
== Support for simple preview materials ==
Very simple versions of the materials are now exported, using only the
viewport diffuse RGB, metallic, and roughness.
When there are multiple materials, the mesh faces are stored as geometry
subset and each material is assigned to the appropriate subset. If there
is only one material this is skipped.
The first material if any) is always applied to the mesh itself
(regardless of the existence of geometry subsets), because the Hydra
viewport doesn't support materials on subsets. See
https://github.com/PixarAnimationStudios/USD/issues/542 for more info.
Note that the geometry subsets are not yet time-sampled, so it may break
when an animated mesh changes topology.
Materials are exported as a flat list under a top-level '/_materials'
namespace. This inhibits instancing of the objects using those
materials, so this is subject to change.
== Hair ==
Only the parent strands are exported, and only with a constant colour.
No UV coordinates, no information about the normals.
== Camera ==
Only perspective cameras are supported for now.
== Particles ==
Particles are only written when they are alive, which means that they
are always visible (there is currently no code that deals with marking
them as invisible outside their lifespan).
Particle-system-instanced objects are exported by suffixing the object
name with the particle's persistent ID, giving each particle XForm a
unique name.
== Instancing/referencing ==
This exporter has experimental support for instancing/referencing.
Dupli-object meshes are now written to USD as references to the original
mesh. This is still very limited in correctness, as there are issues
referencing to materials from a referenced mesh.
I am still committing this, as it gives us a place to start when
continuing the quest for proper instancing in USD.
== Lights ==
USD does not directly support spot lights, so those aren't exported yet.
It's possible to add this in the future via the UsdLuxShapingAPI. The
units used for the light intensity are also still a bit of a mystery.
== Fluid vertex velocities ==
Currently only fluid simulations (not meshes in general) have explicit
vertex velocities. This is the most important case for exporting
velocities, though, as the baked mesh changes topology all the time, and
thus computing the velocities at import time in a post-processing step
is hard.
== The Building Process ==
- USD is built as monolithic library, instead of 25 smaller libraries.
We were linking all of them as 'whole archive' anyway, so this doesn't
affect the final file size. It does, however, make life easier with
respect to linking order, and handling upstream changes.
- The JSON files required by USD are installed into datafiles/usd; they
are required on every platform. Set the `PXR_PATH_DEBUG` to any value
to have the USD library print the paths it uses to find those files.
- USD is patched so that it finds the aforementioned JSON files in a path
that we pass to it from Blender.
- USD is patched to have a `PXR_BUILD_USD_TOOLS` CMake option to disable
building the tools in its `bin` directory. This is sent as a pull
request at https://github.com/PixarAnimationStudios/USD/pull/1048
Users should be able to know explicitly what they are testing.
By having them all enabled we run into a scenario where a new
experimental feature may have been introduced, and the user
is now using it without being even aware of that.

Multisample buffers were used for smooth line drawing. As we now have
an algorithm that doesn't need the multisample buffers we can remove
them.
The user preference for viewport multi_sampling is replaced by single
toggle overlay `use_overlay_smooth_wire`. By default this setting is
enabled as the new drawing is really quick (<1ms) and uses zero hacks.

With the feedback from animators, having a behavior which affects curves

Alt-LMB is used in quite a few areas now, see T69323
using OS-Key allows these conflicts to be avoided.
Currently disabled for WIN32, since it conflicts with the start menu.
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.
