Title: Use a separate matrix to prepend skew

Matrix3D.rawData was showing up as really slow in profiling, so this uses a static matrix filled by copyRawDataFrom to prepend to the skew. Both seem like they require allocating the 16-element vector, but this one is way faster.

It'd be nice to pull this in before the Starling guy finishes with the main skew pull.
