[cairo] render text along path

[Kevin Atkinson]

For what I was doing, I actually want the text to warp, so that's all to the
good.

The remaining challenge is warping text along b-splines or beziers.  You'll
note that in the warpedtext.py example, the paths that the text is warped
along are simple little curves - a spiral and a circle.  I want to warp text
along a spline, and so need to parametrize it by arclength, which is not
completely trivial, and generate a normal to the spline.  I've found a
couple useful references in this regard, but if anyone knows of some
existing code that plays nice with cairo already, it would be greatly
appreciated.

Cheers,

Kevin
