//
// First, when I say I "from XXX.idl", I mean I go into the COM Browser
// ($Microsoft Visual Studio$/Common/Tools/OLEVIEW.EXE), open
// "type libraries", open a specific type library (for quartz for example its
// "ActiveMovie control type library (V1.0)"), save it as an .idl, compile the
// idl using the midl compiler that comes with visual studio
// ($Microsoft Visual Studio$/VC98/bin/midl.exe on VC6) with the /h argument
// to make it generate stubs (a .h & .c file), then clean up the generated
// interfaces I want with the STDMETHOD wrappers and then put them into
// mediactrl.cpp.
//
// According to the MSDN docs, IMediaPlayer requires Windows 98 SE
// or greater. NetShow is available on Windows 3.1 and I'm guessing
// IActiveMovie is too. IMediaPlayer is essentially the Windows Media
// Player 6.4 SDK.
//
// IWMP is from PlayerOCX.idl on PocketPC 2000, which uses CLSID_MediaPlayer
// as well as the main windows line.
//
// Some of these are not used but are kept here for future reference anyway
