/* Example usage:

1. Make a window using Intuition calls

2. Call AMesaCreateContext() to make a rendering context and attach it
   to the window made in step 1.

3. Call AMesaMakeCurrent() to make the context the active one.

4. Make gl* calls to render your graphics.

5. When exiting, call AMesaDestroyContext().
