/*
* ClockView.h
*
* This class handles the drawing of the clock and the moving of the alarm.
* The clock face is drawn into a bitmap and then composited into the
* buffered window before drawing the hands. The hands are stored in the
* server as user paths. Each hand also has a graphic state associated
* with it. Before hand is drawn, its graphic state is installed and then
* rotated to its current angle and then the user path is rendered.
*
* Most of the literals below are for drawing the clock face and the hands.
