44 | /* Other possibilities for default faces: | |
45 | ||
46 | region: Could use SystemHilight, but interferes with our ability to | |
47 | see most syntax highlighting through the region face. | |
48 | ||
49 | modeline: Could use System(In)ActiveTitle, gradient versions (not | |
50 | supported on 95 and NT), but modeline is more like a status bar | |
51 | really (which don't appear to be configurable in Windows). | |
52 | ||
53 | highlight: Could use SystemHotTrackingColor, but it is not supported | |
54 | on Windows 95 or NT, and other apps only seem to use it for menus | |
55 | anyway. | |
