Chimera uses a fragment shader to provide per-pixel lighting (called
"glossy lighting" in Chimera). This gives shinier smoother specular
highlights on surfaces. The same fragment shader does angle-dependent
transparency. This means that a transparent surface at an oblique angle
is more opaque than if the surface is face-on. This darkens parts of
the surface which are edge-on giving improved 3-d appearance.
