Copy a region from source buffer to destination buffer.
If the babl_formats of the buffers are the same, and the tile boundaries align, this will create copy-on-write tiles in the destination buffer.
This function never does any scaling. When src_rect and dst_rect do not have the same width and height, the size of src_rect is used.
