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. Since 1.2
