Subject: fixed shader route in shapes demo:
X-Git-Url: http://git.mutantstargoat.com/user/nuclear/?a=commitdiff_plain;h=eda45df83952e3e92ec4adacc8c942085e132077;p=freeglut

fixed shader route in shapes demo:
- small bug in gl_frustum implementation in matrix lib, element (4,4)
  should be 0
- default OpenGL ambient color is (.2, .2, .2, 1.), not black
little bit of formatting
