Start converting to use atlaspack
Add createGLTexture, analogous to gl-tile-map
Add tile padding, 2x2. Textures now show up but indices are incorrect
Set image name before adding to atlas
Calculate tile index from UV
addedAll -> updateTexture; requires creating mesh (with voxelSideTextureIDs) in updateTexture
Fix textureIndex calculation
Add debug option to write mip levels to canvases in document
Better debugging output for texture index, include UV coords and correct block name
Correct textures and indices, but only with atlasSize 512
Update to rect-mip-map ^0.1.0
Update documentation for atlaspack / rect-tile-map, major change
0.3.0
