Created an attachment (id=51315)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=51315)
Simple implementation of the tolerance-based code

This files contains an example of what the code to create a radial gradient
(given the center, radius, focus, pattern->userspace and target cairo_t) would

Can you please check if it is sufficient to fix your problem?
(Can you also check if my understanding of the SVG specification about the
pattern transform matrix being the inverse of cairo pattern matrices is

If this functions works as expected, we can add it to the cookbook for anybody
wanting only "infocus" radial gradients.
