title: Spherical map transformation
body: <p>I'm using Raphael JS to display a scrollable, zoomable map of the world, which is working fine. But any 2D representation of a globe is going to be distorted. If possible I'd like to transform the map so that the top and bottom are pinched in, to make the map at least a little bit more representative of a globe. Is it possible to achieve such effects with Raphael's matrix, or by hacking deeper into it to insert a manual transformation?</p>
