* does things differently.
+ *
+ *
+ * ==========================================================
+ *
+ * NOTE:
+ *
+ * People just love to hack on this one. I get sent
+ * patches to this all the time saying, ``here, I made
+ * it better!'' Mostly this hasn't been true.
+ *
+ * If you've made changes to xmatrix, when you send me
+ * your patch, please explain, in English, both *what*
+ * your changes are, and *why* you think those changes
+ * make this screensaver behave more like the displays
+ * in the movie did. I'd rather not have to read your
+ * diffs to try and figure that out for myself...
+ *
+ * In particular, note that the characters in the movie
+ * were, in fact, low resolution and somewhat blurry/
+ * washed out. They also definitely scrolled a
+ * character at a time, not a pixel at a time.
