It's 3x2 because you also include translation? Fixed-point 16.16 sounds like a waste for the matrix elements for rotations (elements should be in the range -1/+1). Or do you want to support some scaling as well here? Since useful range and precision are quite different for rotation data and translation, maybe it would make sense to separate them?
