Another possibility to display videos

Now we have only SetPixel, but this is very slow solution, and have some other defects, such as:
- dependence on geometry,
- problem with AR,
- poor performance
- inability to display video in higher resolution.

The best solution will be if, video can by displayed by camera (like gui layer) witch layer depth, in this way user can chose to display video all time on background, on this video can display 3D model ,and on top of it a GUI texture, using only 1 camera.

This way like in ogre3d or OSG ARToolit demos.
