Distort

distort.c
 Drew Olbrich, 1992

 This program demonstrates how texture mapping can be
 used for interactive image distortion effects.

 In this demo, an arbitrarily-sized image is mapped onto
 a large array of texture mapped polygons.  The pop-up menu
 can be used to choose between different kinds of distortion.

 Port to OpenGL
 Nate Robins, 1997

 Changes in the AmigaOS 4.x version:

 Added MiniGL check.
 The menu had to go, as it uses functions not present in MiniGL.
