VideoPlayer: Display frames from the VP9 decoder

Browse source 
For testing purposes, the output buffer is taken directly from the
decoder and displayed in an image widget.

The first keyframe can be displayed, but the second will not decode
so VideoPlayer will stop at frame 0 for now.

This implements a BT.709 YCbCr to RGB conversion in VideoPlayer, but
that should be moved to a library for handling color space conversion.
