Fix multiple UV gizmos being linked at once

This happened when reloading the file after using different gizmos.

Gizmo: use pivot center for UV gizmos

Gizmo: improve 2D arrow select detection

Fixes issue where UV transform circle was being masked by the arrows.

Fluid: Fix broken motion blur for liquids

Added missing resize for vector that holds vert velocities

Fix T72900: Mouse-move causes redraw when gizmos are hidden

Move redraw tagging to the gesture modal operator
to make sure this only runs when it's needed.

Caused by d591c8a350310, which tagged the region to redraw when the
gizmos were tagged to refresh, however they wont redraw when hidden.
Thanks to @jbakker for finding the root cause.

Cleanup: centralize WM_gesture_end call

Prepare for adding extra logic on free (next).

Merge branch 'greasepencil-object' into greasepencil-refactor

Merge branch 'master' into greasepencil-object

Fix T72976: CRASH When Selecting Camera

Industry Compat keymap: Fix gizmos stealing the Alt-key when navigating the viewport

Revert recent change to the particles RNA, and only affect the UI.

Even though the name change is more correct, we don't want to change the API at this time.

GPencil: Continue loop if active frame is NULL

GPencil: Tag datablock when init stroke

Codesogn: Don't capitalize single word

Makes it compatible with Blender's BundleID.

GPencil: Refactor: Remove last occurence of stl->storage

GPencil: Cleanup compiler warnings

Cleanup: Add const

GPencil: Remove unused parameter

Fix T66529: Cycles motion blur render errors with fast rotating objects

In transform_motion_decompose, successive quaternion pairs are checked to be
aligned such that their interpolation is rotation through the shortest angle
between them. If not, the first in the pair was flipped. This can cause
problems for sequences of more than 2 quarternions, since flipping the first
in a pair might misalign the previously pair, if unlucky.

Instead, this change flips the second in the pair, which is safe when
iterating forwards.
