50	* Pixmap Operations : (should be prepended by a colon)
51	* tile Tile image. Scaling/position modifiers above will affect

53	* propscale When scaling, scale proportionally. That is, maintain the
54	* proper aspect ratio for the image. Any portion of the
55	* background not covered by the image is filled with the
