One of the difficulties in implementing pdf gradients with cairo is how to deal
with Postscript functions. For example axial gradients have a linearly varying
parameter but the actual color values are expressed in terms of an arbitrary
Postscript function. ie. the following is a valid axial gradient, r=sin(t),
g=cos(t), b=0, where t varies linearly.
