_cairo_surface_offset_paint() simply transforms the clip and calls
I'm not sure if the infinite loop you are describing is actually
possible (maybe by using a surface as source to draw on that same
Anyway if that's an issue with _cairo_surface_paint(), that will also
be a problem with _cairo_surface_offset_paint().
