This PR fixes #1515, in a way that is less hacky than #1601 by defining octree type and modifying the intersection logic based on which octree we are in. Also recovers total internal reflections. This is because Air has different contexts depending on location. Current changes fix solid block refractions, and partially addresses sub block refractions like glass panes. Currently I cant figure out a good methodology for fixing glass panes that does not break intersection logic. Additionally there are quite a few edge cases to consider like partially water logged glass panes.
Now this makes for some weird views, dont know if these are correct but the above tests makes it seems so, in any case that is a function of refraction and Fresnel code than intersection code
Glass panes are still wrong example:
