Copies a rectangular area from src_pixbuf to dest_pixbuf. Conversion of
pixbuf formats is done automatically.
If the source rectangle overlaps the destination rectangle on the
same pixbuf, it will be overwritten during the copy operation.
Therefore, you can not use this function to scroll a pixbuf.
