repaint(ms) only "tries its best" to do the repaint within the specified
time frame. The timeout only controls expected scheduling, it can't force
the repaint to occur at the specified time because there may be other
things going on.

Typically a separate thread is used to drive the animation and it sleeps
at the approximate frame rate that it wants to achieve while the update
method is robust with respect to missing some frames either due to a
slow processor not being able to keep up or various delays caused by
background processes interfering for short periods of time. The frame
rate you can expect to achieve depends on how complex your animation is
and how fast the platform you are running on.
