33	* search for FILE in the current working directory, and within the	30	* Pixmap geometry string interpretation :
34	* colon-delimited PATHLIST, adding the file extension EXT if required.	31	* Each geometry string contains zero or one scale/position
		32	* adjustment and may optionally be followed by a colon and one or more
		33	* colon-delimited pixmap operations.
		34	* The following table shows the valid geometry strings and their
		35	* affects on the background image :
35	*	36	*
36	* FILE is either semi-colon or zero terminated	37	* WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
		38	* W and H are percentages of the terminal window size.
		39	* X and Y are also percentages; e.g., +50+50 centers
		40	* the image in the window.
		41	* WxH+X Assumes Y == X
		42	* WxH Assumes Y == X == 50 (centers the image)
		43	* W+X+Y Assumes H == W
		44	* W+X Assumes H == W and Y == X
		45	* W Assumes H == W and Y == X == 50
		46	*
		47	* Adjusting position only :
		48	* =+X+Y Set position to X% by Y% (absolute).
		49	* =+X Set position to X% by X%.
		50	* +X+Y Adjust position horizontally X% and vertically Y%
		51	* from current position (relative).
		52	* +X Adjust position horizontally X% and vertically X%
		53	* from current position.
		54	*
		55	* Adjusting scale only :
		56	* Wx0 Multiply horizontal scaling factor by W%
		57	* 0xH Multiply vertical scaling factor by H%
		58	* 0x0 No scaling (show image at normal size).
		59	*
		60	* Pixmap Operations : (should be prepended by a colon)
		61	* tile Tile image. Scaling/position modifiers above will affect
		62	* the tile size and origin.
		63	* propscale When scaling, scale proportionally. That is, maintain the
		64	* proper aspect ratio for the image. Any portion of the
		65	* background not covered by the image is filled with the
		66	* current background color.
		67	* hscale Scale horizontally, tile vertically ?
		68	* vscale Tile horizontally, scale vertically ?
		69	* scale Scale both up and down
		70	* auto Same as 100x100+50+50
