- Forsyth::OptimizeFaces() now has 2 overloads, 1 for uint16_t and one
for uint32_t sized indices. Internally each overload now calls down to
the templated OptimizeFacesImpl() providing the respective index type.
- The new 'vertexBaseIndex' is the starting vertex index
subtracted from each index in indexList to allow safe operation on
multiple objects in a single index buffer.
- Also replaced the interal int typedefs with common types provided by
stdint.h
