# 2.0 Release - Bill Baxter (wbaxter@gmail.com)
# Date:         June 16, 2007
# o Changed to use sizers instead of fixed placement.
# o Made dialog resizeable
# o Added a splitter between file list and view pane
# o Made directory path editable
# o Added an "up" button" to go to the parent dir
# o Changed to show directories in file list
# o Don't select images on double click any more
# o Added a 'broken image' display for files that wx fails to identify
# o Redesigned appearance -- using bitmap buttons now, and rearranged things
# o Fixed display of masked gifs
# o Fixed zooming logic to show shrunken images at correct aspect ratio
# o Added different background modes for preview (white/grey/dark/checkered)
# o Added framing modes for preview (no frame/box frame/tinted border)
# 
#----------------------------------------------------------------------------
#
# 12/08/2003 - Jeff Grimmett (grimmtooth@softhome.net)
#
# o Updated for wx namespace
# o Corrected a nasty bug or two - see comments below.
# o There was a duplicate ImageView.DrawImage() method. Que?
#
