+//
+//####################THE BIG DIRECTSHOW OVERVIEW############################
+//
+//
+// OK... this deserves its own little tutorial. Knowledge of COM and class
+// factories is assumed throughout this code.
+//
+// Basically, the way directshow works is that you tell it to render
+// a file, and it builds and connects a bunch of filters together.
+//
+// There are many, many ways to do this.
+//
+// WAYS TO RENDER A FILE (URLS WORK IN DS ALSO)
+//
+// 1) Create an instance of IGraphBuilder and call RenderFile on it
+// 2) Create an instance of IMediaControl and call RenderFile on it
+// 3) Create an instance of IAMMultiMediaStream, call
+// IAMMultiMediaStream::AddStream and pass an IDirectDraw instance for
+// the video, and pass an IDirectSound(Buffer?) instance or use the
+// default sound renderer, then call RenderFile or RenderMoniker
+// 4) Create a Moniker instance for the file and create and build
+// all of the filtergraph manually
+//
+// Our issue here is that we can't use the default representation of 1 and 2
+// because the IVideoWindow instance hogs a lot of the useful window
+// messages such as WM_SETCURSOR.
+//
+// Solution #1 was to use #3 by creating a seperate IDirectDraw instance
+// for our window and blitting to that through a thread... unfortunately
+// the blitting resizing is very low quality and its quite slow.
+//
+// The current way is to use windowless rendering and have directshow
+// do all the DirectDraw-style clipping to our window
+//
+// ~~~~~~~~~~~~~~AFTER RENDERING THE FILE~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+//
+// When done rendering the file, we need to get several interfaces from
+// either a IMediaControl or IGraphBuilder instance -
+//
+// IMediaPosition - we can set the rate with this... we can also get
+// positions and set positions through this with REFTIME (double) instead
+// of the normal LONGLONG that IAMMultiMediaStream and IMediaControl use
+//
+// IBasicAudio - we need this for setting/getting the volume
+//
+// Interfaces that we don't use but might be useful one day -
+//
+// IDirectDrawVideo - you can get this through the IFilter returned
+// from L"Video Renderer" filter from FindFilter on the IGraphBuilder.
+// Through this we can set the IDirectDraw instance DrawShow uses.
+//
+// ~~~~~~~~~~~~~~STOPPING~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+//
+// There are two ways we can do this -
+// 1) Have a thread compare the current position to the end position
+// about every 10 milliseconds
+// 2) Have IMediaSeekingEx send a message to a windowproc or signal a
+// windows event
+//
+// Note that we can do these both, I.E. if an IMediaSeekingEx interface
+// is unavailable we can check the position instead of an event
+//
