Add FALLBACK mode to paginated surface
The PDF surface needs to know when the fallback images start so it can
close off the content stream and create a knockout transparency group
for the fallback images. Currently it does this by looking for
operations with CAIRO_OPERATOR_SOURCE. PDF returns unsupported for
_SOURCE during the analysis phase so _SOURCE will never appear during
native operations. However this prevents the PDF surface from
supporting _SOURCE operations that can be natively supported. For
example a _SOURCE operation with nothing painting under it can be
converted to _OVER and natively supported.
A third mode, CAIRO_PAGINATED_MODE_FALLBACK, has been added. The
paginated surface will set this mode before it paints finer-grained
fallback images.
