72	*
73	* Adjusting scale only :
74	* Wx0 Multiply horizontal scaling factor by W%
75	* 0xH Multiply vertical scaling factor by H%
76	* 0x0 No scaling (show image at normal size).

78	* Pixmap Operations : (should be prepended by a colon)
79	* tile Tile image. Scaling/position modifiers above will affect
80	* the tile size and origin.
81	* propscale When scaling, scale proportionally. That is, maintain the
82	* proper aspect ratio for the image. Any portion of the

84	* current background color.
85	* hscale Scale horizontally, tile vertically ?
