Revision: 40730
          http://scummvm.svn.sourceforge.net/scummvm/?rev=40730&view=rev
Author:   thebluegr

Log Message:
-----------
Changed calculations based on frame delay to be based on the scale of 1ms, not 1/100. This fixes the FLIC player and also makes the overall code a bit clearer and easier to understand
