(block) lighting
- lighting via light emitting blocks and brightness from the
- manhattan distance to a light source. light levels should be
- cached with each block and only recalculated on update
+ light levels are roughtly implemented. the shader has to be
+ adjusted so they actually have an impact on the resulting color
gravity

- going from one chunk to the neighboring is highly wasteful as of
- now. each chunk should have links to its neighbours. also, maybe
- the chunk loader should keep an index of interesting, if not all
- chunks by position, possibly base-relative
