40	* adjustment and may optionally be followed by a colon and one or more
41	* colon-delimited pixmap operations.
42	* The following table shows the valid geometry strings and their
43	* effects on the background image :
44	*
45	* WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
46	* W and H are percentages of the terminal window size.
47	* X and Y are also percentages; e.g., +50+50 centers
48	* the image in the window.
49	*
50	* Pixmap Operations : (should be prepended by a colon)
51	* tile Tile image. Scaling/position modifiers above will affect
52	* the tile size and origin.
53	* propscale When scaling, scale proportionally. That is, maintain the
54	* proper aspect ratio for the image. Any portion of the
55	* background not covered by the image is filled with the
56	* current background color.
57	* hscale Scale horizontally, tile vertically ?
58	* vscale Tile horizontally, scale vertically ?
59	* scale Scale both up and down
60	* auto Same as 100x100+50+50
