Christoph Oelckers 27799def63 - rewrote movie player so that the decoder backends only perform the decoding but do not draw the frames themselves.
This caused twq problems:

1. It made it impossible to let the client apply effects to the video.
2. The client had no control when rendering stopped.

Now the backends only provide a texture handle that the client must draw. One immediate benefit is that Blood's fixed viewport scaling is now available to all video formats.
