/*
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
