/*
    Default QT Palette Generator
    by Mike Melanson (mike at multimedia.cx)
    based on code ripped out of the XAnim media application:
      http://xanim.polter.net/

    This program generates a C header file with the default palette
    colors used in Quicktime multimedia files. To use this program:
      1) Define whether you want the colors printed in RGBA or BGRA order.
         The program will print RGBA order unless you uncomment the line:
         //#define PRINT_BGRA
      2) Compile the program:
         cc qtcolors.c -o qtcolors
      3) Run the program and pipe the output to a .h file:
         qtcolors > qtpalette.h
