The basic idea is to render the glowing parts of the scene to an offscreen buffer, then take
that buffer and blur it. After it is sufficiently blurred, re-apply that image back to
the normal screen using a additive blending. To blur the scene I use a vertex program to supply
four texture coordinate offsets that allow 'peeking' into adjacent pixels. In the register
combiner (pixel shader), I combine the adjacent pixels using a weighting factor. - Aurelio
