Implemented window coord mirroring for RTL. This

is only implemented for *setting* the coordinates
    which is enough for wxSizers and 99% or other
    dialogs to work.
  Also reversed the meaning of wxStaticText alignment
    in RTL mode. It is possible that later versions
    of GTK actually do that themselves. (?)
