-  About pens, brushes, and the autoSetting flag:
-
-  Under X, pens and brushes control some of the same X drawing parameters.
-  Therefore, it is impossible to independently maintain the current pen and the
-  current brush. Also, some settings depend on the current logical function. The
-  m_currentFill, etc. instance variables remember state across the brush and
-  pen.
-
-  Since pens are used more than brushes, the autoSetting flag is used to
-  indicate that a brush was recently used, and SetPen must be called to
-  reinstall the current pen's parameters. If autoSetting includes 0x2, then the
-  pens color may need to be set based on XOR.
-
-  There is, unfortunately, some confusion between setting the current pen/brush
-  and actually installing the brush/pen parameters. Both functionalies are
-  perform by SetPen and SetBrush. C'est la vie.
