Sprite2D Rect Editor

This addon allows easier editing of the region_rect property of Sprite2D nodes. The addon should be compatible with Godot 4.1 through 4.3. It may work for other 4.x releases but I haven't tested them.

Resizing Handles

When a Sprite2D is selected in the editor and has region_enabled checked, additional handles will appear on each side of the Sprite2D. Dragging these handles will resize the region rect in the given direction while adjusting the node's position and the region's x/y/width/height properties such that the opposite edge stays put.

Caveats

• The Sprite2D must have global_rotation set to a multiple of 2π (e.g. 0). I didn't want to have to figure out how to measure drag distance along any arbitrary axis, but pull requests are welcome.
• The handles will always snap to 8px increments. Godot doesn't provide a way for addons to fetch the editor's configured snap settings (see this issue). You can change the snap distance for your project's needs by changing the grid_size constant in plugin.gd.

Autorect

As a bonus, the plugin adds an "autorect" button to the Sprite2D inspector. When pressed, it sets region_enabled to true and sets the region rect to the size of the image. This is in contrast to the default behavior which just sets the rect's dimensions to 0 when you enable the region.
