I wonder if it is possible to create a TV screen emitting light and displaying a picture. Or a stove emitting light from the glass and displaying a texture of a fire.

I have read the SVG mini guide, and it says we must define a diameter for a light source, but I wonder if:
- it is possible to define a rectangular surface as a light source ?
- make a light that doesn't blind when we look at it ?

By the same way, I also thought to make the rectangular glass of a window emit light without blinding, in order to simulate the natural light.

If it is not possible with the actual version of SweetHome 3D, I wonder if it could be possible in a future version ?
