You could use the Window X/Y offset to do what you want - I think it's
more correct than using the crop as it's post-perspective in terms of
it's transform (which I think is more correct - but could be completely
wrong). You'll have to mess around with numbers to get it right though,
if you're not sure about this perhaps your could create a number of
reference objects to define your field of views (a bit like a look at
null) and mess around with the numbers until they fit.
