 * The deal is this:
 *   Call W_Initialize(), and then you may call any of the listed fuinctions.
 *   Also, externals you are allowed to pass or use include W_BigFont,
 *     W_RegularFont, W_UnderlineFont, W_HighlightFont, W_White, W_Black,
 *     W_Red, W_Green, W_Yellow, W_Cyan, W_Grey, W_Textwidth, and W_Textheight.
