Map VDPAU video surfaces to an OpenGL texture.

Note

There can only be one VDPAU context mapped to an OpenGL context.

We use a VdpVideoMixer to complete the conversion from YUV to RGB. Hence the returned texture is RGB... We could use GL_NV_vdpau_interop2 to return raw YUV frames.

Reimplemented from MythOpenGLInterop.
