If we're looking at radial gradient correctness could we actually 
define clearly what the radial gradient is supposed to compute first?  
Right now there are rather weird discontinuities which occur 
sometimes, such as when the focal point moves outside of the outer 
circle.  I've also seen some very odd looking vertical banding.
