has to care about refresh rates. Also changed Screen::GetMode() (formerly Resolution()) to return all interesting values, so that hopefully no one will call it anymore like RootLayer::SetScreens() did. Greatly improved the horrible RootLayer::SetScreens(). The app_server is now able to deal with failing HWInterface::SetMode() calls; in this case, it will fall back to the hardware's current mode. This now also works correctly in combination with the vesa driver, so that you don't have to compile the app_server with the same resolution you boot in anymore. SetMode() now always returns if it succeeded or not. Renamed RootLayer::fScreenXYResolution to fScreenWidth/Height respectively. Removed the useless DisplayDriver::DisplayMode() method. Added B_GET_DISPLAY_MODE to the required accelerant hooks. Some minor cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12831 a95241bf-73f2-0310-859d-f6bbb57e9c96
