USD import option description typo.

Fixed typo in Import USD Preview option description.

USDImportParams designated initialization.

Now using designated initializers when constructing the import
params struct, to help future-proof the code if struct members
are changed or reordered. (Per suggestion by Campbell in his
review of the patch.)

adaptive_cloth: AdaptiveMesh: set_edge_sizes()

Based on the `Sizing` stored in the `Vert`s of the `Edge`s, store the
"size" of the `Edge` in it's extra data.

adaptive_cloth: Mesh: change visibility of many utility functions

Make them protected instead of private.

Functions that get some element from the `Mesh` (maybe through other
elements) can be used by derived classes. It might make sense to make
these functions public directly instead of protected but will take
that decision later.

adaptive_cloth: Vert: get_uv() and get_uv_mut()

adaptive_cloth: Mesh: get extra data from elements

Simple functions to get extra data from elements.
It is possible make `extra_data` public but this reduces readability
of the code. By having these functions, intent is obvious.

GPencil: Use Shift key to keep pivot in Center for scale

GPencil: Create missing materials

Still need more work to avoid duplications

GPencil: More work on asset import

Remove strokes if cancel.
Cleanup code

Merge branch 'master' into soc-2021-knife-tools

Knife: Fixed undo when cut is on edge

Fixed undo with cut segments along mesh edges and cut segments not over a mesh.
Cut segments along a mesh edge also no longer show as they are redundant.

Fix conditions to start Thumbnail Job

Jobs started when view changes or images not loading. Multiple strips now
work without error but slow. In the order of strips thumbs are loaded.

Merge branch 'master' into soc-2021-vse-strip-thumbnails

Use multithreading to set face varying data.

Merge branch 'master' into geometry-nodes-unnamed-attributes

Knife: Moved midpoint snapping to SHIFT and ignore snapping to CTRL

Midpoint snapping was originally CTRL but when undo was added as CTRL-Z this caused some strange behaviour.
Therefore midpoint snapping was moved to ALT but this broke when alt-tabbing.
By moving midpoint snapping to SHIFT and ignore snapping to CTRL there are no more problems.

Use the new dissolve function for all operators.

GPencil: New pivot for Scale and cage with rotation icon

GPencil: Fix cage scale (pending pivot point)

Improved link dissolve method that supports multiple nodes.

The new functions keep links between the selected nodes intact when
disconnecting them from their surroundings.
