/* Sample Usage:
*
* 1. Call DMesaCreateVisual() to initialize graphics.
* 2. Call DMesaCreateContext() to create a DMesa rendering context.
* 3. Call DMesaCreateBuffer() to define the window.
* 4. Call DMesaMakeCurrent() to bind the DMesaBuffer to a DMesaContext.
* 5. Make gl* calls to render your graphics.
* 6. Use DMesaSwapBuffers() when double buffering to swap front/back buffers.
* 7. Before exiting, destroy DMesaBuffer, DMesaContext and DMesaVisual.
