# 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
