+ About pens, brushes, and the m_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 m_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 m_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.
