Extents of Zero when decoding #279

Open flippmoke opened 6 years ago

Currently it is possible to have issues in our scaling during decoding in the case where decoding a tile with an extent of zero. This causes a divide by zero issue and we should prevent this from proceeding further once it is detecting in decoding.
