Snow cover on the terrain

[BAWV12]

I would like to see in P3D snow coverage based on the METAR report, humidity, temperatures and terrain elevation via terrain shader. Very nice example is open source simulator FlightGear. With proper color mixing is possible obtain seasons. Then we will not need gigabytes of seasonal textures.

I agree, I think is a good idea to use shaders instead of textures.
