Looking at it now, I see that there will be a couple of problems.  First,
it can't properly deal with vectors with an X value of zero.  If you fix that
by testing the green or blue values as well, it still can't properly deal
with zero vectors.  To fix it, make another local that's equal to
rgbft 0 + (1 + A) ,
then compare that vector's red and filter components as well.  Only if both
comparisons are equal is it a scalar (because 1+A is either a vector or a 
scalar, whichever A was, and either A or 1+A is going to have a nonzero X
component.)
