High-performance 3D on Haiku

See: Gaming on Haiku - #89 by cocobean

GLTeapot is a simple app but it does show a basic benchmark. The difference in discussions is that GLTeapot is not a true representation of real 3D graphics benchmarking in full consideration. No high-end polygon counts, phong shading, bump mapping, or tessellations. At least, not in this current app iteration…

This is where the line in the sand is drawn by most enthusiasts…using 3DMark… etc, etc…
