34	* These GEOM strings indicate absolute size/position:	47	* Pixmap geometry string interpretation :
35	* @ `WxH+X+Y'	48	* Each geometry string contains zero or one scale/position
36	* @ `WxH+X' -> Y = X	49	* adjustment and may optionally be followed by a colon and one or more
37	* @ `WxH' -> Y = X = 50	50	* colon-delimited pixmap operations.
38	* @ `W+X+Y' -> H = W	51	* The following table shows the valid geometry strings and their
39	* @ `W+X' -> H = W, Y = X	52	* affects on the background image :
40	* @ `W' -> H = W, X = Y = 50
41	* @ `0xH' -> H *= H/100, X = Y = 50 (W unchanged)
42	* @ `Wx0' -> W *= W/100, X = Y = 50 (H unchanged)
43	* @ `=+X+Y' -> (H, W unchanged)
44	* @ `=+X' -> Y = X (H, W unchanged)
45	*	53	*
46	* These GEOM strings adjust position relative to current position:	54	* WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
47	* @ `+X+Y'	55	* W and H are percentages of the terminal window size.
48	* @ `+X' -> Y = X	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
49	*	63	*
50	* And this GEOM string is for querying current scale/position:	64	* Adjusting position only :
51	* @ `?'	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
