Temporarily redirects drawing to an intermediate surface known as a
group. The redirection lasts until the group is completed by a call
to cairo_pop_group() or cairo_pop_group_to_source(). These calls
provide the result of any drawing to the group as a pattern,
(either as an explicit object, or set as the source pattern).
The group will have a content type of content. The ability to
control this content type is the only distinction between this
function and cairo_push_group() which you should see for a more
detailed description of group rendering.
