- 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.
