[cairo] Switching to Evas Canvas over LGPL

[M. Evans]

Carl,

Indeed, as you say, "it's all about freedom, remember?" -- so persuade 
me that Cairo does or will offer technical advantages over Evas, which, 
like Antigrain.com, retains a nice, friendly license.

Explain what Cairo does that Evas does not -- if anything. Then we can 
decide whether Cairo's technical merits outweigh its new license and 
make an informed choice.  In this manner you can help us to exercise our 
freedom.
