   FIXME FIXME FIXME:
    - extract different backends in different files (better yet, make backends
      dynamically loadable...), they have nothing to do with each other and
      this file is huge and also separate the standard contents from our code
      itself

//
//  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.
//
//  Some of these are not used but are kept here for future reference anyway
