PDF::API3::Compat::API2::Basic::PDF::Page->new($pdf, CW$parent, CW$index)
Creates a new page based on a pages object (perhaps the root object).
The page is also added to the parent at this point, so pages are ordered in
a PDF document in the order in which they are created rather than in the order
they are closed.
Only the essential elements in the page dictionary are created here, all others
are either optional or can be inherited.
The optional index value indicates the index in the parent list that this page
should be inserted (so that new pages need not be appended)
Adds the string to the currently active stream for this page. If no stream
exists, then one is created and added to the list of streams for this page.
The slightly cryptic name is an aim to keep it short given the number of times
people are likely to have to type it.
Ships the page out to the given output file context
