Thanks for the suggestion. Sadly the same thing happens.
I've also tried using the built-in projection object, like so:
proj = Projection("+proj=merc +datum=WGS84")
c0 = proj.forward(Coord(-180,85))
c1 = proj.forward(Coord(180,-85))
bbox = Envelope(c0.x, c0.y, c1.x, c1.y)
(85 in there isn't exact, but would have been good enough)
And I've also changed the styles to only render lines (no fill) in
case it was a layering issue. No luck!
Tom.
