mesh blueprint element winding transforms

[cyrush]

Create a general system for mapping from between different sets of element vertex winding orders.

This may include describing the set of possible permutations for each element and having folks identify which case they are using.

Pseudo propsal:

    "elements": 
      {
        "shape": "quad",
        "winding": 0
        "connectivity": ...
      }

Where winding is an optional number that provides an index that corresponds to a permutation in a documented permutation ordering
