/*
* VIDIX - VIDeo Interface for *niX.
*
* This interface is introduced as universal one to MPEG decoder,
* Back End Scaler (BES) and YUV2RGB hw accelerators.
*
* In the future it may be expanded up to capturing and audio things.
* Main goal of this this interface imlpementation is providing DGA
* everywhere where it's possible (unlike X11 and other).
*
* This interface is based on v4l2, fbvid.h, mga_vid.h projects
* and personally my ideas.
*
* NOTE: This interface is introduced as driver interface.
