OK,

nice piece of non help ;o) - but it did work....

This gets the job done - it clips everything to the West of -135. and
everything East of -55.

map_contour -> SetProperty, clip_planes=[[-1.,0.,0.,-135.],
[1.,0.,0.,55.]]

It "kind of" makes sense but is making my head hurt a little (I know
I'm too precious).
Anyhow, following the logic of the 2 clip planes above I should be
able to work out other ones.

Err, thanks David.
