-# BACKFACE_CULLING avoid drawing triangles that are not facing forward
-# CLIPPING turn on clipping (you really always want this)
-# DEPTH_TEST enable the z buffer for depth testing
-# EXTRA_INLINE allow the compiler to inline even more aggressively
-# LIGHTING turn the lights on (experimental)
-# NDEBUG disable assertions and other nonessential checks
-# FIND_NORMALS[=n] pre-compute vertex normals at loading time
-# set to 1 for per-face normals, 2 for averaged normals
-# RASTER_STATS print triangle count and optimization savings at the end
-# RENDER_PROGRESS print progress while drawing the scene
-# RENDER_TIMER add a timer to see how long the renderer takes
-# SMOOTH_COLOR interpolate colors smoothly between triangle vertices
