wxWidgets/include/wx/mstream.h
Robert Roebling ed58dbeab6 Changed a few #include <xxx.h> to #include "xxx.h"
Added endl operator to wxTextStream
  Corrrected a few misbehaviours in wxFileDialog,
  Corrected tab traversal a bit
  Corrected wxImage::SetData() to not copy, but take
    the data and care for ref couting as well
