The UpDown control specified by id will change it's values while the user holds
down the mouse button. You can alter the rate of the change by using this routine.
The Times parameter is a list of pairs of values, in which the first of a pair
is the number of seconds to elapse (from the time the button was pressed) before changing,
and the second is the (positive) increment to change the current value by.
Example:
setAcceleration(myUpDown, { {1,2}, {3,4}, {5, 8}, {7,16} } )
