fix#581
## Major features
- Heightmap overhaul!!!!
- normal maps (bump maps)
- smoothness (gloss) and metallic maps
- tiling versions of texture/normal/smoothness/metallic maps for finer
up-close detail
- texture painting
- use the red, green, blue, and alpha channels of a blend texture to
determine where each set of tile textures goes.
- you can also use black spots on the blend map to include a fifth
"base" set of tile textures for where there's a lack of
red/blue/blue/alpha.
