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