/**
* \file fixedtip.h Metacity fixed tooltip routine
*
* Sometimes we want to display a small floating rectangle with helpful
* text near the pointer. For example, if the user holds the mouse over
* the maximise button, we can display a tooltip saying "Maximize".
* The text is localised, of course.
*
* This file contains the functions to create and delete these tooltips.
*
* \todo Since we now consider MetaDisplay a singleton, there can be
* only one tooltip per display; this might quite simply live in
* display.c. Alternatively, it could move to frames.c, which
* is the only place this business is called anyway.
*
* \todo Apparently some UI needs changing (check bugzilla)
