/**

* Reads the mouse and/or keyboard data sent from a GraphicsWindow, and
|

|
|
* transmits it down the data graph.
|
||
|
|
*
|
||
|
|
* The mouse and keyboard devices are bundled together into one device here,
|
||
|
|
* because they interrelate so much. A mouse might be constrained by the
|
||
|
|
* holding down of the shift key, for instance, or the clicking of the mouse
|
||
|
|
* button might be handled in much the same way as a keyboard key.
|
||
|
|
*
|
||
|
|
* Mouse data is sent down the data graph as an x,y position as well as the
|
||
|
|
* set of buttons currently being held down; keyboard data is sent down as a
|
||
|
|
* set of keypress events in an EventDataTransition. To throw these events to
|
||
|
|
* the system, you must attach an EventThrower to the MouseAndKeyboard object;
|
||
|
|
* otherwise, the events will be discarded.
