// Class : MouseWatcher
// Description : This TFormer maintains a list of rectangular regions
// on the screen that are considered special mouse
// regions; typically these will be click buttons. When
// the mouse passes in or out of one of these regions,
// or when a button is clicked while the mouse is in one
// of these regions, an event is thrown.
//
// Mouse events may also be suppressed from the rest of
// the datagraph in these special regions.
//
// This class can also implement a software mouse
// pointer by automatically generating a transform to
// apply to a piece of geometry placed under the 2-d
// scene graph. It will move the geometry around
// according to the mouse's known position.
