00005     This class encapsulates the 'lpc_swim' functions provided by mbed for drawing on the display.
00006     We are using these to draw our own profile graphs on our own bitmaps, 
00007     which should give an improved appearance by comparison with easyGUI.
00008     
00009     This class (as usual) is a singleton - there is only one display, after all.
