title: wxPython SetLayoutDirection Doesn't Work On Mac
body: <p>On Windows with wxPython 3.0.2 SetLayoutDirection works as expected in htmlWindow. SetLayoutDirection(2) will allow me to display RTL texts. However, with the same version on Mac it does not work. It is always the default LTR text flow. Plus GetLayoutDirection always returns 0 even after SetLayoutDirection(2) is supposedly set.</p>
  
  <p>Was this feature missed on the Mac build? Is there a fix or workaround?</p>
