Blits a "src_rect" [Rect2] from "src" [Image] to this [Image] using a "mask" [Image] on coordinates "dest". Alpha channel is required for "mask", will copy src pixel onto dest if the corresponding mask pixel's alpha value is not 0. "src" [Image] and "mask" [Image] *must* have the same size (width and height) but they can have different formats
