* clutter/clutter-main.c (_clutter_id_to_color): When choosing a pick color, set all but the most significant of the unused bits. This should make make it more likely that the GL implementation will round down to the right value. * tests/test-pick.c: Test case for picking. It creates 192 actors at known positions and stores their gids. It then calls clutter_stage_get_actor_at_pos with each position to check that the right gid is returned. * tests/Makefile.am (noinst_PROGRAMS): Add test-pick
