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