- *    XParseGeometry parses strings of the form
- *   "=<width>x<height>{+-}<xoffset>{+-}<yoffset>", where
- *   width, height, xoffset, and yoffset are unsigned integers.
- *   Example:  "=80x24+300-49"
- *   The equal sign is optional.
- *   It returns a bitmask that indicates which of the four values
- *   were actually found in the string.  For each value found,
- *   the corresponding argument is updated;  for each value
- *   not found, the corresponding argument is left unchanged.
