+ * Modified 12/91 by Dean Luick. Tim graciously donated this piece of code
+ * from his program ghostview, an X11 front end for ghostscript.
+ *
+ * + Make the cancel button optional.
+ * + Put an #ifdef SPECIAL_CMAP around code to fix a colormap bug.
+ * We don't need it here.
+ * + Add the function positionpopup() from another part of ghostview
+ * to this code.
+ *
+ * Modified 2/93, Various.
+ * + Added workaround for SYSV include problem.
+ * + Changed the default width response text widget to be as wide as the
+ * window itself. Suggestion from David E. Wexelblat, dwex@goblin.org.
