//-----------------Introduction----------------------------------------------
// This backend is for Desktops with either WMP 9 or 10 and Windows
// mobile (5.0, some 2003 SmartPhones etc.) WMP 10 only (9 has no automation
// interface but you can hack it with message hacks to play through
// a currently running instance of media player).
//
// There are quite a few WMP 10 interfaces and unlike other media
// backends we actually set it to automatically play files as it has
// as huge caveat that you cannot (technically) obtain media information
// from IWMPMedia including duration and video size until a media file
// has literally started to play. There is a hack (and indeed we have
// it within this file) to enable duration getting from a non-playing
// file, but there is no hack I (RN) know of to get the video size from
// a file that isn't playing.
//
// The workaround for this is to send the wxEVT_MEDIA_LOADED when the file
// is about to be played - and if the user didn't change the state of the
// media (m_bWasStateChanged), when set it back to the stop state.
//
// The ActiveX control itself is particularily stubborn, calling
// IOleInPlaceSite::OnPosRectChange every file change trying to set itself
// to something different then what we told it to before.
//
