13 About pens, brushes, and the autoSetting flag:
14
15 Under X, pens and brushes control some of the same X drawing
16 parameters. Therefore, it is impossible to independently maintain
17 the current pen and the current brush. Also, some settings depend on
18 the current logical function. The m_currentFill, etc. instance
19 variables remember state across the brush and pen.
20
21 Since pens are used more than brushes, the autoSetting flag is used to
22 indicate that a brush was recently used, and SetPen must be called to
23 reinstall the current pen's parameters. If autoSetting includes 0x2, then the
24 pens color may need to be set based on XOR.
25
26 There is, unfortunately, some confusion between setting the current pen/brush
27 and actually installing the brush/pen parameters. Both functionalies are
28 perform by SetPen and SetBrush. C'est la vie.
