  27 /*  FUNCTION
  28         Swaps the back with front buffers. MUST BE used to display the effect
  29         of rendering onto the target RastPort, since AROSMesa always work in
  30         double buffer mode.
  31
  32     INPUTS
  33         amesa - GL rendering context on which swap is to be performed.
