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	*
72	* Pixmap Operations : (should be prepended by a colon)
73	* tile Tile image. Scaling/position modifiers above will affect
74	* the tile size and origin.
75	* propscale When scaling, scale proportionally. That is, maintain the
76	* proper aspect ratio for the image. Any portion of the
77	* background not covered by the image is filled with the
78	* current background color.
79	* hscale Scale horizontally, tile vertically ?
80	* vscale Tile horizontally, scale vertically ?
81	* scale Scale both up and down
82	* auto Same as 100x100+50+50
