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