42 * The following table shows the valid geometry strings and their

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.

50 * Pixmap Operations : (should be prepended by a colon)
