work okay

vtkOutputWindow ow
     ow DisplayText [ow Print]

Ok, except for the massive recompilation, does anyone have any serious
objections to this:

void vtkObject::PrintWindow()
{
  char *vtkmsgbuff;
  ostrstream vtkmsg;
  this->Print(vtkmsg);
  vtkmsgbuff = vtkmsg.str();
  vtkOutputWindowDisplayText(vtkmsgbuff);
  vtkmsg.rdbuf()->freeze(0);
}
