Comment(by strk):
r8134 fixes this case by having gserialized_read_gbox_p correctly produce
the BOX "as if it was just read from cache" even in the POINT and 2-points
LINE case.
I'm not completely sure about what would happen with other kind of
geometries as I see gserialized_get_gbox_p calls lwgeom_calculate_gbox in
that case, which probably doesn't produce a FLOAT-aware version of them.
I guess it will be worth adding much more tests for that. Probably
involving postgis_dropbbox and a MULTIPOINT would do. I'll leave this
ticket in case someone wants to work on the tests (paul, you do want to
work on the tests don't you ? :)
