58	* adjustment and may optionally be followed by a colon and one or more

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