Subject: Re: Rendering Plugin drawing above a video
If you use non-SDK mechanisms for drawing you have no guarantee that it
will work in all environments.
For instance, the method you mentioned may not work in a situation where
someone implements their own windowless site.
You also need to be careful about assumptions you make about the client
your renderer is running in. It might be in RealPlayer, it might be in the
ActiveX control or Netscape plugin. It might be in some custom client, or
details about the client that you assumed would always be true when you
wrote your renderer may change. (I've seen plenty of custom renderers
crash in the ActiveX control or Netscape plugin because the render made
some false assumptions about its window or the container application.)
If you're going to go outside of the SDK in order to accomplish something
you should be careful about what assumptions you make and you should be
prepared to fail gracefully
