-       Arcball, as described by Ken
-       Shoemake in Graphics Gems IV.
-       This class takes as input mouse events (mouse down, mouse drag,
-       mouse up), and creates the appropriate quaternions and 4x4 matrices
-       to represent the rotation given by the mouse.
-
-       This class is used as follows:
-       - initialize [either in the constructor or with set_params()], the
-       center position (x,y) of the arcball on the screen, and the radius
-       - on mouse down, call mouse_down(x,y) with the mouse position
-       - as the mouse is dragged, repeatedly call mouse_motion() with the
-       current x and y positions.  One can optionally pass in the current
-       state of the SHIFT, ALT, and CONTROL keys (passing zero if keys
-       are not pressed, non-zero otherwise), which constrains
-       the rotation to certain axes (X for CONTROL, Y for ALT).
-       - when the mouse button is released, call mouse_up()
-
-       Axis constraints can also be explicitly set with the
-       set_constraints() function.
-
-       The current rotation is stored in the 4x4 float matrix 'rot'.
-       It is also stored in the quaternion 'q_now'.
