I have a few questions about this.
1. So if a tick is a specified number of milliseconds then what happens
when too much is happening during a cycle for the computer to be able to
handle in "tick" milliseconds?
2. Or instead if the tick is in Squeak time units what relationship does
it have to the passage of time my watch shows?
Underlying my questions is the desire to be able to set a speed so that
a car takes, for example, exactly 5 seconds to travel 100 units
(pixels?) at a constant speed.
