Improved editing for transformed shapes (again)

[Pizzaandy]

• Adjusted mouse delta while editing vertices and control points on shapes where global_transform != identity
• "Set Pivot" action now works as expected on shapes where global_transform != identity
• Fixed a small issue where the editor buttons do not disappear after a shape is deselected
• Test change: ActionSetPivot action no longer takes a Transform2D argument

Very nice PR! Gave it a short testing session: all the actions work as expected, and undo-redo performs without failure.

After more testing, I found a small issue still lurking with cutting a shape into two shapes. I attach video of the issue:

Ah, good find! I think the cut mode still assumes that global_transform = identity. I'll take a look at that this week.

Fixed the issue: the SS2D_Shape.clone method only copied over the position and scale rather than the entire transform. I also decided to increase the size of some icons and improve the contrast on shape outlines.

Tried it in the editor and it's all good! 👍

Thanks for the feedback - I'll try to get those changes in later today.

LGTM 👍
