[Fluxus] 2d overlay

[gabor papp]

i managed to solve it in a bit complicated way.
i built a new camera, set orthographic projection for the original 
camera, hid the overlay for the new camera, and all other objects for 
the original camera.
i attached the script which draws a background. overlay can be done 
similarly.
suggestions are welcome if a simpler solution exists.

best,
gabor
