[osg-users] More lights in scene!

[Terry Welsh]

Neat. I did the same thing for a game I wrote, but I used custom
shader-based lights instead of OpenGL lights, and I used 4 lights
instead of 8. The most interesting takeaway was that applying  shaders
for 0, 1, 2, 3, or 4 lights (5 different shaders) was very slow due to
shader swapping. The fastest combination I found was to only compile
shaders for 0 or 4 lights, and if I only needed to apply 1, 2, or 3
lights I could set some of their color uniforms to black.
