[Papervision3D] 2D coords from 3D in AS2

[jlm]

I found that I need to use delegate for sorting if I want access to the
instances properties in the sort function ie:

_arr.sort(Delegate.create(this, distance))

and I have been thinking I need to get into the mesh code, but my
assumptions on getting the corners are slightly floored, have to leave it
for the moment and get other things working.

anyone know the theory of how to sort the faces to get corners and I will
try to code it but can't think of best concept because furthest from center
would not work always.
