* Setting the depth to 1 for VGA mode in frame_buffer_console_init() was not
a good idea; it didn't have any consequences in there, but actually broke the app_server's support for the VGA mode. * Cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32181 a95241bf-73f2-0310-859d-f6bbb57e9c96
