Title: Make the isChunkValidForRender check a lot faster.

Half of the render time was spent to check if a chunk is valid for render.

By precalculating this value when the chunks get ready/ get disposed, the frame rate
increases for me at a certain world with view distance ultra from
about 40 to 50 FRPS.
