Copies [param src_rect] from [param src] image to this image at coordinates [param dst], clipped accordingly to both image bounds. This image and [param src] image [b]must[/b] have the same format. [param src_rect] with non-positive size is treated as empty.
+ [b]Note:[/b] The alpha channel data in [param src] will overwrite the corresponding data in this image at the target position. To blend alpha channels, use [method blend_rect] instead.
