PaintableT.addOnInvalidateSize

Emitted when the intrinsic size of the @paintable changes.

This means the values reported by at least one of [method@Gdk.Paintable.get_intrinsic_width], [method@Gdk.Paintable.get_intrinsic_height] or [method@Gdk.Paintable.get_intrinsic_aspect_ratio] has changed.

Examples for such an event would be a paintable displaying the contents of a toplevel surface being resized.
