Implementing self-illuminating textures shouldn't require anything more complex than what Minetest already does with lighting. It already sets custom texture brightness depending on the light level in each node. There just needs to be a way to override that for particular parts of a texture. Just like we can add a file "mymod_mynode_normal.png" containing a normal map, we should be able to add a file "mymod_mynode_glow.png" with an illumination map. That sort of thing has been done in games since the very first 3D graphics appeared.
