34	* These GEOM strings indicate absolute size/position:	30	* Pixmap geometry string interpretation :
35	* @ `WxH+X+Y'	31	* Each geometry string contains zero or one scale/position
36	* @ `WxH+X' -> Y = X	32	* adjustment and may optionally be followed by a colon and one or more
37	* @ `WxH' -> Y = X = 50	33	* colon-delimited pixmap operations.
38	* @ `W+X+Y' -> H = W	34	* The following table shows the valid geometry strings and their
39	* @ `W+X' -> H = W, Y = X	35	* 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	*	36	*
46	* These GEOM strings adjust position relative to current position:	37	* WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
47	* @ `+X+Y'	38	* W and H are percentages of the terminal window size.
48	* @ `+X' -> Y = X	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
49	*	46	*
50	* And this GEOM string is for querying current scale/position:	47	* Adjusting position only :
51	* @ `?'	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
