33	* search for FILE in the current working directory, and within the	47	* Pixmap geometry string interpretation :
34	* colon-delimited PATHLIST, adding the file extension EXT if required.	48	* Each geometry string contains zero or one scale/position
		49	* adjustment and may optionally be followed by a colon and one or more
		50	* colon-delimited pixmap operations.
		51	* The following table shows the valid geometry strings and their
		52	* affects on the background image :
35	*	53	*
36	* FILE is either semi-colon or zero terminated	54	* WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
		55	* W and H are percentages of the terminal window size.
		56	* X and Y are also percentages; e.g., +50+50 centers
		57	* the image in the window.
		58	* WxH+X Assumes Y == X
		59	* WxH Assumes Y == X == 50 (centers the image)
		60	* W+X+Y Assumes H == W
		61	* W+X Assumes H == W and Y == X
		62	* W Assumes H == W and Y == X == 50
		63	*
		64	* Adjusting position only :
		65	* =+X+Y Set position to X% by Y% (absolute).
		66	* =+X Set position to X% by X%.
		67	* +X+Y Adjust position horizontally X% and vertically Y%
		68	* from current position (relative).
		69	* +X Adjust position horizontally X% and vertically X%
		70	* from current position.
		71	*
		72	* Adjusting scale only :
		73	* Wx0 Multiply horizontal scaling factor by W%
		74	* 0xH Multiply vertical scaling factor by H%
		75	* 0x0 No scaling (show image at normal size).
		76	*
		77	* Pixmap Operations : (should be prepended by a colon)
		78	* tile Tile image. Scaling/position modifiers above will affect
		79	* the tile size and origin.
		80	* propscale When scaling, scale proportionally. That is, maintain the
		81	* proper aspect ratio for the image. Any portion of the
		82	* background not covered by the image is filled with the
		83	* current background color.
		84	* hscale Scale horizontally, tile vertically ?
		85	* vscale Tile horizontally, scale vertically ?
		86	* scale Scale both up and down
		87	* auto Same as 100x100+50+50
