The raw flags were previously unused in wxGTK but hardware key code is an important information which may be useful to the application, so pass it in the flags (this is rather symmetric with passing lParam in it under MSW as lParam contains the scan code, among other things). Also document the meaning of raw key code and flags in all the major ports. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@65893 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
