Is it possible to do column operations (addition, subtraction) directly on an XMMATRIX (i.e. XMMATRIX alternative for XMVECTOR swizzle operations) without using _XM_NO_INTRINSICS_?

I use these operations for creating the view frustum planes directly from the transformation matrices.

XMMATRIX contains four SSE registers, containing four rows of data. You could transpose it to get four registers holding four columns of data.

Works like a charm!
