59	* WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.

69	* Adjusting position only :
70	* =+X+Y Set position to X% by Y% (absolute).

72	* +X+Y Adjust position horizontally X% and vertically Y%
73	* from current position (relative).
74	* +X Adjust position horizontally X% and vertically X%
75	* from current position.
76	*
77	* Adjusting scale only :
78	* Wx0 Multiply horizontal scaling factor by W%
79	* 0xH Multiply vertical scaling factor by H%
80	* 0x0 No scaling (show image at normal size).
81	*
82	* Pixmap Operations : (should be prepended by a colon)
83	* tile Tile image. Scaling/position modifiers above will affect
84	* the tile size and origin.
85	* propscale When scaling, scale proportionally. That is, maintain the
86	* proper aspect ratio for the image. Any portion of the
87	* background not covered by the image is filled with the
88	* current background color.
89	* hscale Scale horizontally, tile vertically ?
90	* vscale Tile horizontally, scale vertically ?
91	* scale Scale both up and down
92	* auto Same as 100x100+50+50
