Bryce Denney 0a5ce87b15 - now instead of having the simulation thread send repaint messages to
the wxwindows thread, it just sets a boolean flag needRefresh.  Meanwhile, a
  wxTimer running in wall clock time (as opposed to sim time) triggers a
  repaint only if the the boolean is true.
- now MyRefresh is implemented by just setting needRefresh=true.
- make graphics_tile_update call MyRefresh.
- make dimension_update call MyRefresh.
