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