// NOTE: Be sure you have defined your bitmaps by assigning them a resource
// id of a quoted string (i.e. "BITMAP1" instead of ID_BITMAP1) since
// you will be designating the bitmaps by their quoted resource string
// in this file.
// Be sure that you do not leave a space between the quoted bitmap
// resource name and the \b identifier when setting up your array.
// "BITMAP1\b" = correct
// "BITMAP1 \b" = incorrect
// Thanks to Gerry Shaw for submitting code to fix the redraw so that only
// the actual display window refreshes each time instead of the entire
// dialog which was causing annoying flicker.
