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