4f87524821 Switched back to using uniforms for light parameters, as using the fixed
function state killed my frame rate.  Also cleaned up some of the location
tracking.

4f4b4c08bb Restore specular lighting--but, per the OpenGL spec, shut off specular
contribution if the surface isn't facing the light.

float specular = max(0.0, dot(normalize(gl_LightSource[0].position + vec4(0.0, 0.0, 1.0, 0.0)), normalizedNormal));
to
    float specular = max(0.0, dot(gl_LightSource[0].position, normalizedNormal));

Calculation for specular value has to be done like in all other shaders with the unmodified unnormalized lightsource position. Otherwise the specular effect will have weird behaviour.
