   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.
