/* 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.
