 *
 * a Cube is a Control containing exactly one CubeCell.  the idea is to let a
 * user manipulate a cube with a dark (front) face that represents the window
 * on a 3d space.
 *
 * initially, the cube appears as a dark square.  next, by clicking on a vertex
 * or a face, the user rotates the cube.  it's possible to do a full turn
 * without a mouseup.
 *
 * instance vars
 * none.
 *
 * public methods
 * -initFrame:......................initializing a new Cube
 * -(BOOL)acceptsFirstMouse.........YES
 * -reset...........................set to frontview
 * -setmatrix:(float*)set...........copy 9 floats into cube tfmatrix
 * -getmatrix:(float*)get...........copy 9 floats from cube tfmatrix
