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.

Fix T89868: Crash showing thumbnail of wide-aspect image

Scaling down images could create images with a width or height of zero.

Clamp at 1 to prevent a crash, also add an assert to scaling functions.

Ref D11956

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.

Knife: New depth check toggle

Pressing 'V' will toggle depth testing on and off for the knife tool cut lines.
When a cut involves a lot of cut segments on an object it can be very helpful to hide cut segments which should be blocked from view by the object that is being cut.

UV: Keymaps for offsetting selected UVs

Adds keymaps to offset selected UVs by a fixed distance in a specified direction.

Knife: Remove entire drag cut on undo

Previously when a knife cut was created by holding left click and dragging, undo would only undo each segment of the dragged cut individually.
This change makes it so the entire dragged cut is removed when undone.
Some refactors to the undo code were required to implement this.

GPencil: More work in Scale transform

Merge remote-tracking branch 'origin/master' into temp-lineart-contained

LineArt: set new cut flag when a middle is needed.

Fixed two warnings on curve fillet code

Sculpt dyntopo:

* Prototyped a threaded bmesh->Mesh converter function. It's about
20-30% faster. Currently disabled.
* Tried to fix more of the bugs when stepping between sculpt and
other undo step types in the global undo stack.

Knife: Fixed distance and angle measurements not working with undo

Moved data required for distance and angle measurements into new struct KnifeMeasureData.
Now this struct is saved on the undo stack which fixes distance and angle measurements when undo is used.

Merge branch 'master' into temp_bmesh_multires

Removed the NODE_OT_duplicate_move_keep_inputs operator.

This is a variation of NODE_OT_duplicate_move with the "keep_inputs"
property set. This can be done in keymaps instead.
