remove forgotten noise.h includes
common_ply.h: ignore invalid faces with duplicated points
(this solves visual flaws in dragon model)
extend loadShape for loading triangles
realtime_dragon.cc demo: add kd-tree dump/load functionality,
add colored perlin cloud texture
#!/usr/bin/python
# this demo needs dragon model from
