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.
