/*     Rotator

An applet that animates a sequence of frames stored in a single file.
Based on JavaSpin by Blake Stone (http://www.dkw.com/bstone).

http://rsb.info.nih.gov/nih-image/Java/Rotator/

Parameters:
  image   Name of image file, no default
  frames  Number of frames, default = 'columns' * 'rows'
  rate    Rate in frames per second, default = 6
  columns Number of frames across the image, default = 'frames'
  rows    Number of frames down the image, default = 1
