+/* Found in Don Hopkins' .plan file:
+ *
+ *   The color situation is a total flying circus.  The X approach to
+ *   device independence is to treat everything like a MicroVax framebuffer
+ *   on acid.  A truely portable X application is required to act like the
+ *   persistent customer in the Monty Python ``Cheese Shop'' sketch.  Even
+ *   the simplest applications must answer many difficult questions, like:
+ *
+ *   WHAT IS YOUR DISPLAY?
+ *       display = XOpenDisplay("unix:0");
+ *   WHAT IS YOUR ROOT?
+ *       root = RootWindow(display, DefaultScreen(display));
+ *   AND WHAT IS YOUR WINDOW?
+ *       win = XCreateSimpleWindow(display, root, 0, 0, 256, 256, 1,
+ *                                 BlackPixel(display, DefaultScreen(display)),
+ *                                 WhitePixel(display, DefaultScreen(display)))
+ *   OH ALL RIGHT, YOU CAN GO ON.
+ *
+ *   WHAT IS YOUR DISPLAY?
+ *         display = XOpenDisplay("unix:0");
+ *   WHAT IS YOUR COLORMAP?
+ *         cmap = DefaultColormap(display, DefaultScreen(display));
+ *   AND WHAT IS YOUR FAVORITE COLOR?
+ *         favorite_color = 0; / * Black. * /
+ *         / * Whoops! No, I mean: * /
+ *         favorite_color = BlackPixel(display, DefaultScreen(display));
+ *         / * AAAYYYYEEEEE!! (client dumps core & falls into the chasm) * /
+ *
+ *   WHAT IS YOUR DISPLAY?
+ *         display = XOpenDisplay("unix:0");
+ *   WHAT IS YOUR VISUAL?
+ *         struct XVisualInfo vinfo;
+ *         if (XMatchVisualInfo(display, DefaultScreen(display),
+ *                              8, PseudoColor, &vinfo) != 0)
+ *            visual = vinfo.visual;
+ *   AND WHAT IS THE NET SPEED VELOCITY OF AN XConfigureWindow REQUEST?
+ *         / * Is that a SubStructureRedirectMask or a ResizeRedirectMask? * /
+ *   WHAT?! HOW AM I SUPPOSED TO KNOW THAT?
+ *   AAAAUUUGGGHHH!!!! (server dumps core & falls into the chasm)
