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