Hey @kangax , was thinking of taking a stab at this. Off the top of my head, here's what needs to be done:

• Add a type property to the options expected by .setGradientFill() that'd have values linear or radial
• Use .createRadialGradient() to implement the visuals

Any gotchas in implementing this that I should know of?

Sounds good! Well, createRadialGradient has different syntax (radius 1, radius 2 instead of x1,y1 and x2,y2) so we'll need different parameters to accomodate that.

Aside from that, there's SVG output to take care of, as usual.
