* Removed DisplaySupport.h, wasn't needed anymore. * Removed private color set functions from InterfaceDefs.cpp - we might want something similar, but definitely not like that. * Minor cleanup, added some missing licenses. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16831 a95241bf-73f2-0310-859d-f6bbb57e9c96
