This checkin enables mozilla to support the printing of selection, the printing of page ranges, and

the printing of headers and footers.
Printing of selection is implemented by the frames figuring out if they are in the selection and painting
if they or not they they don't paint. This also only allows the printing of the first page of
selections, alothough it is well documented where this is implemeted so it can be removed.
