	It'd be rather nice to have some parameter names rather than just
'long' 'int' etc. etc ;-) I assume that the last four are pixel
co-ordinates to render ? (perhaps doubles would be better), and the
first long is ? I imagine we want to be able to fetch the size of pages
in the same co-ordinate system (?) or do we use the existing render
interface for that ?

	One of the big missing nasties is a standard signal/slot mechanism that
is part of the language, and maps (where possible) to a native language
construct.

	HTH,
