// This is a long string in XBM image format. It defines an image.
// This is an ASCII format, which means we can easily manipulate it
// in JavaScript, but also means that it is not compact. This is only
// a 22x22 pixel image. The real power of this technique comes, of course
// when we start generating XBM data dynamically at run time instead of
// using a static string as we do here.

// involve specifying a MIME type when opening the document. Here we
// create a new window, and then use a javascript: URL as the SRC of an
// inline <IMG>. This is an XBM image embedded in a text/html document,
// so we can display text, anchors, etc.

// We can also use the javascript: URL with the BACKGROUND tag of the
// <BODY> tag. XBM is a black-on-white image format, but note how the
// BGCOLOR tag can replace the white background.
