The test was incorrectly translating the "target" of the context instead of the "group target" (i.e. the current destination). "cairo-test-suite -a" runs the tests on similar surfaces created using cairo_push_group (), thus without this change the device-offset did not affect the real destination surface. Fixes clip-device-offset.
