- * This module implements a text overlay for a video image. Currently it
- * supports a fixed overlay or reading the text from a file. The string
- * is passed through strftime so that it is easy to imprint the date and
- * time onto the image.
- *
- * You may also overlay an image (even semi-transparent) like TV stations do.
- * You may move either the text or the image around your video to create
- * scrolling credits, for example.
- *
- * Text fonts are being looked for in FONTPATH
- *
- * Options:
- *
- * -C <rgb.txt>         The filename to read RGB color names from
- *                      Defaults if none specified:
- *                      /usr/share/X11/rgb.txt
- *                      /usr/lib/X11/rgb.txt
- * -c <color>           The color of the text
- * -F <fontname>        The font face and size
- * -t <text>            The text
- * -f <filename>        The filename to read text from
- * -x <expression>      X coordinate of text or image
- * -y <expression>      Y coordinate of text or image
- * -i <filename>        The filename to read a image from
- * -R <expression>      Value for R color
- * -G <expression>      Value for G color
- * -B <expression>      Value for B color
- * -A <expression>      Value for Alpha channel
- *
- * Expressions are functions of:
- *      N  // frame number (starting at zero)
- *      H  // frame height
- *      W  // frame width
- *      h  // image height
- *      w  // image width
- *      X  // previous x
- *      Y  // previous y
- *

  * This module is very much intended as an example of what could be done.

  * One caution is that this is an expensive process -- in particular the
