Better Mitochondria

[thejmazz]

• [x] spinning atp synthase barrels
• [x] ~~proper face material indices when merging ATP synthase geometry~~
• [x] face colors to keep different colours on one mesh with BufferGeometry (synthase colours)
• [x] better cristae distribution - even on both sides, no big gap
• [x] inner and outer membrane phospholipid textures
• [ ] better LOD, no empty object at lowest level. instead use simple block representation or billboards or otherwise. autogenerate billboard using 4 cameras and render to texture
• [ ] improved camera/controls
• [ ] improve UV stretching/compression
• [ ] find good amount of ETCs w/o having to hide them completely at zoom out
