| 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. |
