00028 //       Class : MouseAndKeyboard
00029 // Description : Reads the mouse and/or keyboard data sent from a
00030 //               GraphicsWindow, and transmits it down the data graph.
00031 //
00032 //               The mouse and keyboard devices are bundled together
00033 //               into one device here, because they interrelate so
00034 //               much.  A mouse might be constrained by the holding
00035 //               down of the shift key, for instance, or the clicking
00036 //               of the mouse button might be handled in much the same
00037 //               way as a keyboard key.
00038 //
00039 //               Mouse data is sent down the data graph as an x,y
00040 //               position as well as the set of buttons currently
00041 //               being held down; keyboard data is sent down as a set
00042 //               of keypress events in an EventDataTransition.  To
00043 //               throw these events to the system, you must attach an
00044 //               EventThrower to the MouseAndKeyboard object;
00045 //               otherwise, the events will be discarded.
