Merge branch 'master' into xr-controller-support

XR: Add grab navigation operator

Similar to the XR grab transform operator but applies deltas to the
navigation matrix instead of objects. Supports bimanual interaction
for viewer/navigation scaling and locks for rotation and scale.

XR: Smooth transition between modal actions

Although only one modal action is allowed at a time, if another
modal action is pressed when the current modal action ends, then
transition immediately to that one.

XR: Fixes/adjustments when viewer scale != 1.0

This corrects some clipping and shading issues when a scale factor
is applied to the XR viewmat. Also fixes the viewer pose calculation
with VR navigation.

Remove duplicate file

Was renamed to "wm_xr_action.c".

Nicer utility function to update attribute types.

VSE: Improved Snapping

Patch is WIP

Add snapping settings to header.
Add varoius snapping options.

Differential Revision: https://developer.blender.org/D11646

General tree type function to set attribute shape.

Use the tree type to make sure attribute sockets
are displayed as squares.

It's not ideal that this property is per socket
and not tied directly to the socket type, but this
will do for now.

adaptive_cloth: mesh: initial class setup

Simple implementation of attribute get node.

This does not currently check for existing attributes, which would be
mostly a helper feature to avoid invalid references further downstream.

Rename "Attribute Load" node to "Attribute Get".

This is to avoid the impression that it loads data when in fact it only
creates a reference to an attribute.

Allow implicit attribute-to-string conversion.

This will allow connecting attributes directly to old-style string
input sockets, at least until most nodes can be converted.

Added USDStageReader::handle_prim() function.

Per suggestion by Sybren in his review, moved code from
the static _handlePrim() function to a USDStageReader private
member function. This helps simplify the code as the new
function requires fewer argumants. Also performed minor
cleanup of the function implementation.

USD Import: fixed typo in comment.

USD Import: removed unused ImportSettings member.

ImportSettings::vel_scale was unused and has bee removed.
