+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.
