Emission textures for building windows on night maps

[MirceaKitsune]

Little suggestion that popped to mind today and I wanted to throw in. Since 0.24 we've had the ability to select night time on some maps (sadly very few of them). Could this be accompanies by glow textures for windows on buildings, ideally as a map setting so the map / biome can define intensity? This would require creating an emissive texture for all buildings that have windows, but hopefully it's not a big task and may be an option for the next release.

 

On that note it would be nice if buildings containing flames (eg: some faction's version of the temple) could emit light. I assume this would require larger changes to the lighting system though, IIRC it only knows to work with one light source which is the sun / moon. So I understand it may not happen until later on at best.
