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