-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.
