Per-pixel lighting

[James W. <ja...@fr...>]

I'm thinking of adding a per-pixel lighting option when the hardware 
supports OpenGL Shading Language.  It would have to be an option because 
it will slow down rendering some.  Any opinions as to how this option 
should be selected ... an object property on the renderer, or a new 
flavor of illumination shader, or an object property on the Phong 
illumination shader, or something else?
