Context.pushGroupWithContent

Temporarily redirects drawing to an intermediate surface known as a group. The redirection lasts until the group is completed by a call to [cairo.context.Context.popGroup] or [cairo.context.Context.popGroupToSource]. 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.context.Context.pushGroup] which you should see for a more detailed description of group rendering.
