Move signatures and ObjectConstants to Metadata.
Next step toward separating TwistyObject metadata.
Big step toward separating TwistyObject metadata.
change complexity from int to float.
remove 'MESH_NICE'
separate ObjectSiguature into its own package and separate the BandagedSignatures out of it.
Support drawing stickers with multiple holes in them.
correct face shapes (post-new MeshPolygon normal computation)
Actually use the 'overridable rotation factors' feature and tweat the factors of many objects.
Lower Square-0's complexity to 1.
Add Square-0
