Projective light cone

Due to its intrinsic nature of texture, the shadow map looks squared.

A nice way to improve its appearance is to use the very same coordinates that project the shadow to map an additional bitmap, which simulates the bottom of the light cone produced by the "spotlight".

Now it would be cool to simulate the whole light cone by using some kind of volumetric escamotage.
