#
#    This is a very simple sample program that demonstrates how to use Color
#    QuickDraw.  It is about two pages of code, and does nothing more than open
#    a color window and draw randomly colored ovals in the window.
#
#    The purpose is to show how to get some initial results with Color QuickDraw.
#    It is a complete program and is very short to be as clear as possible.
#
#    It does not have an Event Loop.  It is not fully functional in the sense that
#    it does not do all the things you would expect a well behaved Macintosh
#    program to do, like size the window naturally, have an event loop, use menus,
#    etc.
#
#    See Sample and TESample for the general structure and MultiFinder techniques that
#    we recommend that you use when building a new application.

//    Version 1.0:    6/2/88
//                    7/20/88     DJB    Converted to C
//
//    purpose        To demonstrate a simple color App using Color QuickDraw.
//                        It draws colored balls in a color window, then uses colored
//                        text inverted in the ball.  The ball location and color is Random.
//
//                        This program was written by Bo3b Johnson, 1/88.
//
//                        The inverted Bob text was a Skippy Blair special concept,
//                        kept for obvious aesthetic reasons.

//MW -cut out some other program descriptions.-

//MW ** Metrowerks note **
//   All changed code by Metrowerks is commented by "//MW".
//   There is one type of modification to the original source:
//   • Added argument type and return type to function definitions.
//       In order to pass with extended error checking on.
