This seems fine, but will potentially slow down the loading of graphics
since each sprite, once loaded, must be copied.  And I don't know if
imlib actually does anything useful (faster drawing, etc.) by
associating the pixmap and its mask.  If it does, then it would make
more sense to do it the other way around (make all sprites imlib pixmaps).
