* moved the system default font functionality into the DesktopSettings class. * ServerFont::SetStyle() is now a public method. * Improved font fallback routines: they will never end up without a font if there is at least one font installed. * fixed some minor bugs in the DecorManager. * Decorator now get a DesktopSettings object passed - dunno if that's a good idea (since we'll have to open the DesktopSettings header), but it works for now (and something like this is probably needed anyway). * a clean ServerFont is now set to the system default font - and not to the (user chosen) desktop default font anymore (since the font manager doesn't know about that one). * Improved font directory scanning in the font manager a bit, it's now using find_directory() instead of hard-coded paths. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14666 a95241bf-73f2-0310-859d-f6bbb57e9c96
