Explain how we can simplify the radial gradient computation

Soeren rightfully complained that I had removed all the comments from
André's patch, most importantly that explain why the transformation is
valid. So add a few details to show that B varies linearly across the
scanline and how we can therefore reduce the per-pixel cost of evaluating
B.
