Bug 4310: Ancestry>Pedigree View is largely broken with Gtk-OSX

Browse Source 
Don't retain a reference to the CairoContext by setting self.context (or
self.cairocontext). That context is invalidated on the return from the 
handler anyway with a context.restore(), so there's no benefit to 
keeping it around.
