Once you've drawn something and **before** you cr.fill() or cr.stroke(), you can record the path to a list of points for later use. This recipe includes an algorithm to tell whether a point is within that path's area or not. It prints to the console, so it's not exactly bling, but it's pretty nifty for all that. Go see <http://local.wasp.uwa.edu.au/~pbourke/geometry/insidepoly/> for the theory behind the voodoo :)
-I am trying to contact the author of the algorithm to double check that it can appear here. Will update.
Jeff Muizelaar informed me that Cairo has a built-in function to do this anyway. See code listing 2.
