+/*
+ * Problems with this code:
+ *   1. The text window behaves like it's only a few lines high, 
+ *      scrolling in response to Return when the insertion point 
+ *      is nowhere near the last line.
+ *   2. The attempt to insert text with XawTextReplace() core dumps.
+ *   3. I haven't found a way to write a callback that triggers on Return 
+ *      and yields the line before the return.  The explanation at
+ *      http://www.linuxjunkies.org/programming/GUI/xwindow/x11/text.html
+ *      hints that this may be difficult.
+ *
+ * The functional goal is this:
+ *    1. Button pushes should be able to insert commands at the buffer's
+ *       current insertion point.
+ *    2. When a user finishes a command with Return, a callback should
+ *       receive the line of input typed.
+ * 
+ * All the input passed to the game in back of this will be lines full
+ * of commands generated either by typing into the text buffer directly 
+ * or by button presses that generate text unto the buffer.
