I continue to wish we had a vector type as IntSize is weird.  I can't remember why we don't have one.  Is it because we don't want another type representing a pair of ints?  Or is it naming? Or something else.

I wish we had a better type for this type of vector.

The typecast to float here seems unnecessary. I expect the compiler can handle float * int * float -> float without a typecast.
