Floating point 3-vector, aligned to be internally identical to a vfloat4. The way it differs from vfloat4 is that all of he load functions only load three values, and all the stores only store 3 values. The vast majority of ops just fall back to the vfloat4 version, and so will operate on the 4th component, but we won't care about that results.
