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

51965fd283 changed 
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.

22598ceb4f Optimizations for occlusion blur (the main one being that we only need to

and sample between the texels).

b05b43f027 Render to texture first, rather than copying from the frame buffer. Copying 
from the frame buffer requires it to have an alpha channel, which actually
does something on OS X (meaning we have to set it to 1.0).  We're going to
want to render to texture anyway for SSAO (or other effects).

5138f62aef Use the "proper" alpha value (i.e., the one from the original shader). This 
makes the sky somewhat darker, but that probably just means we need more
scattering or a brighter sun.
