+ time is required for a transition, and the number of steps that'll take,
+ and sets up the _trans_timer function to do the work. If the transition
+ time is set to 0 ms it just calls _trans_timer once with _steps equal to
+ zero so that the transition happens instantaneously. This occurs on
+ windows as opacity changes cause flicker there.
