title: How is windows' cursor smoothing/acceleration calculated?
body: <p>I am trying to program my own cursor in an application, but I find that windows' acceleration and/or smoothing of a cursor is much more easy and precise to use than just moving the custom cursor by raising the input magnitude of the mouse to a power. 
  If it's a speed curve that has simply been optimized for this accuracy, is there anywhere I can find this curve, or algorithm, because it would be best to have least noticeable difference in using the custom cursor as opposed to the acceleration normally used in windows?</p>
