Got another question here. I dont think you can use maxextent to get the 
required correction to apply since a user may change it. I also notice 
that the logic used seems to apply to rectilinear projections - it 
wouldnt be accurate for say conic projections. It seems that accurate 
way to transform geometry crossing the 180 is unproject to pixel then 
reproject again but without 180 corrections.
