There were several problems in the old random calculation:
* Different result in the viewport and render.
* Noise "pop" in some frames.
* Random number was calculated every time the file was opened, so get different results.
Now, instead to calculate the random numbers when n number of frames changed, the random values are calculated using a unique seed by stroke.
Also, a new Seed parameter has been added and this adds more control in the noise generated. This value can be animated and get more variations.

The first issue was that we were still working around a Xorg bug that
has been solved since a very long time:
https://bugs.freedesktop.org/show_bug.cgi?id=22515
The second issue was that the global "confirm on release for mouse
clicks" was used for keyboard shortcuts as well.
This patch introduces the same presets that are used for proportional editing in the brush falloff menu. The user can select any of these presets or use the regular custom falloff curve. The presets are hardcoded formulas, so the falloff curve is not used when they are active.
This change improves the general feeling of the brushes and it is more convenient and simpler to use. The CUSTOM curve option should now be used in the case that an unusual deformation is needed, in other cases, the hardcoded curve presets should be the default.
The smooth curve presets is a must in the grab brush, as it fixes the deformation issue with the current custom curve setting. The user may try to adjust the deformation by tweaking the curve, but it is nearly impossible to replicate this desired behavior.

Other brushes that are included in the sculpt branch also rely on this as they need specific hardcoded falloffs to produce the desired effect.

This commit adds support for the WebM container. Previously we only
supported the WebM/VP9 video codec, but still required that it was
stored in a Matroska, MP4, or other compatible container format.

This is useful when popovers are launched from operators
instead of as button popover types.
Where the connection between the button and the popover is useful to keep.
These panels were using the old names, but now they are not grease pencil, but annotations.
Also removed old Tools panel. This must be replaced with new Toolbar
Such reload can no longer happen directly and is to be done via dependency
graph.
Eventually, the movie cache will become shared across all copies of the
clip, but even then we still need to have dependency graph mechanism because
we need to update FFmpeg animation handle (which can not be shared across
the copies).
The environment variable to locate system data-files was
ignored by toolbar icons.
Add bpy.utils.system_resource
to match Blender's internal data-file access.
Some external tools seem to have issues with the definition
of Collada <transparency> - a float value in range (0,1).
However it is possible to use the <transparent> color as a container
for the <transparency> value. This seems to be a more reliable
method to export transparency values from Blender PBSDF Shaders.
The relevant documentation is in the collada 1.14 reference manual,
page 7-5 about the usage of transparent and transparency.
This fix makes export and import of the <transparency>
and <transparent> values more convenient and more reliable.

The options of the material are from object material not pinned material.
If the brush is pinned, the material must be the brush material and not the object material.
Based on feedback from T66675, the current interface is confusing,
leading to users accidentally overwriting their preferences.
Now, once factory settings are loaded preferences are not saved
and the save button is shown (as when auto-save is disabled).
Tool tips note that factory settings require manual saving
afterwards.
Also rename preference menu items for better consistency
(settings/state -> preferences).
Some values (not properly handled by do_versions?) could cause
'rna_backup_restore()' to throw an error resulting in the whole preview
generation not being saved to the .blend file.
I've checked folowwing demo files:
- race_spaceship.blend
- wasp_bot.blend
Here the offending seetings were:
- `UnitSettings` (`length_unit`, ...)
- `FFmpegSettings` (`ffmpeg_preset`, ...)
For now, these are now excluded in `exclude_props`

When a mesh datablock is pinned in the properties panel,
`context.object` is `None`. This in turn causes `obj.mode` to raise an
`AttributeError` exception as `None.mode` doesn't exist.
Since there is no (fast/simple) way to check whether the owning object
is in edit mode or not, the properties will be disabled. Not ideal, but
better than spewing an exception on every panel draw.
