Adds elapsed time; returns animation progress in interval 0..maxProgress while timeElapsed is between 0 and maxInterval; when interval exceeded, progress is maxProgress

restart with same max interval and progress
start new animation interval
returns time elapsed since start
Returns true if animation is finished
get current time interval
override current time interval, retaining the same progress %
