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 can be tested using the 'Experimental' preferences section
or selected in the key-map editor.
This commit is a full refactor of the grease pencil modules including Draw Engine, Modifiers, VFX, depsgraph update, improvements in operators and conversion of Sculpt and Weight paint tools to real brushes.
Also, a huge code cleanup has been done at all levels.
Thanks to @fclem for his work and yo @pepeland and @mendio for the testing and help in the development.

Addons option
This removes the 'use_owner' option feature from rB61c8ed40f5df.
(this wasnt working well when addons are enabled and when switching

Now Addon filtering is just bypassed for Import/Export menus.

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]`.

Actually, to purge orphans datablock you need go to Outliner, enable Orphan mode and press Purge button (that sometimes is out of the view because the window is too narrow).
To have this option hidden make very difficult to users use and understand what means orphan data, so this patch just adds a new Clean Up menu to File menu with this option. This menu could be used in the future for more clean up options. To have a general Clean Up menu is common used in other softwares.

This makes a number of changes to the tool settings brush UI:
- All brush-related controls are now grouped together, so you can see which items are brush settings are which are not. Previously it was all jumbled together.
- The brush picker is in a separate panel, so that you can switch brushes without worrying about the settings, or vice versa.
- Custom Icon settings moved from the Display settings(now known as Cursor) to the Brushes panel.
- UnifiedPaintSettings panels are removed and the contained options are now next to their relevant setting with a globe icon toggle. This is not displayed in the header.
- 2D Falloff and Absolute Jitter toggles were changed into enums, to make it clearer what happens when they are on or off.
- Adjust Strength for Spacing option was in the Options panel in some modes, but in the Stroke panel in others. It is now always under Stroke.
- Display (now Cursor) panel was reorganized, settings renamed.
- 2-option enums are annoying as a drop-down menu, so they are now drawn with expand=True.
- Smooth Stroke and Stabilizer options in grease pencil and other paint modes are now both called "Stabilize Stroke", for consistency and clarity.
- De-duplicated some drawing code between various painting modes' brush options. I tried to keep de-duplication reasonable and easy to follow.
- A few more tweaks - see D5928 for the extensive list.

This commit introduces the first version of an exporter to Pixar's
Universal Scene Description (USD) format.

- 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
Also adds a generic popover that can be used whenever an active tool has too
many settings than can fit in the horizontal area. The popover calls the active
tool's draw_settings with "extra" set to True.
Implement T66304 as an experimental option,
available under the preferences "Experimental" section.
- When enabled most tools in the 3D view have a gizmo.
- Dragging outside the gizmo uses the 'fallback' tool.
- The fallback tool can be changed or disabled in the tool options
or from a pie menu (Alt-W).
Add new icons and panels Grease Pencil Dopesheet to manage layers without having the properties panel visible.
Also, the icons are in the same order in Dopesheet, Layers and Material list to keep consistency.
As the number of columns for icons is limited to 3 and we also need use a factor, I have impleted the change using slider area. Also, the slider option is enabled by default for 2D Template.

The behavior for loading factory settings wasn't clear for users.
This commit changes the behavior:
- Loading factory settings always disables auto-save
for the current session.
- The internal setting to skip saving on exit is now exposed
in the preferences (when enabled).
- The menu item "Load Factory Settings (Temporary)" has been removed
since it's always temporary.
This way users can always reset factory settings without
having to consider the combination of options that might cause their
preferences to be overwritten at exit.
If they want to enable auto-save for the current session
this can be done from the preferences.

- Move Preferences to the top as it is used often.
- Introduce two new sub-menus
- About - links from Help menu, plus link to license section in blender.org
- Support Blender - dev fund, store, they used to be in Help menu.
Help menu:
- Add links to Tutorials and Support section in blender.org
- Add link to Developer Documentation (wiki)
- Always show Python API Reference link

- Only show the top-bar (by default)
in paint work-spaces (sculpt / texture-paint / grease-pencil).
- Add an active-tool panel to the sidebar.
- Split 3D view tabs into (Item / Tool / View).

Further work is needed for the top-bar and image-editor.
I also had to make the "New" operator a submenu in the
`File Context Menu`, so that you can still select the template.
This partially solves T61599. Currently the confirm dialog
is not shown when an already existing file is opened.
Implementing that requires a bit more work and will be
