VZ		 13 About pens, brushes, and the autoSetting flag:
14
15 Under X, pens and brushes control some of the same X drawing parameters.
16 Therefore, it is impossible to independently maintain the current pen and the
17 current brush. Also, some settings depend on the current logical function. The
18 m_currentFill, etc. instance variables remember state across the brush and
19 pen.
20
21 Since pens are used more than brushes, the autoSetting flag is used to
22 indicate that a brush was recently used, and SetPen must be called to
23 reinstall the current pen's parameters. If autoSetting includes 0x2, then the
24 pens color may need to be set based on XOR.
25
26 There is, unfortunately, some confusion between setting the current pen/brush
27 and actually installing the brush/pen parameters. Both functionalies are
28 perform by SetPen and SetBrush. C'est la vie.
