  Adds a property editor for an individual property. The [param editor] control must extend [EditorProperty].
+ There can be multiple property editors for a property. If [param add_to_end] is [code]true[/code], this newly added editor will be displayed after all the other editors of the property whose [param add_to_end] is [code]false[/code]. For example, the editor uses this parameter to add an "Edit Region" button for [member Sprite2D.region_rect] below the regular [Rect2] editor.
