+ 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 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
+ 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 autoSetting includes 0x2, then the
+ 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
