Implement push_group/pop_group
This patch adds the following API calls:
cairo_push_group
cairo_push_group_with_content
cairo_pop_group
cairo_pop_group_to_source
cairo_get_group_target
These methods support implementing layers on top of a cairo context,
allowing for drawing with transparency and temporary buffering.
cairo_get_group_target allows an app to get access to the actual surface
created by the last push_group call, in case itneeds to perform native
drawing to it.
