I'm willing to bet that the handedness will be changed when the matrix's
determinant is negative. (That is, the 3x3 matrix you get when ignoring the
last row.)
In other words, yes, it should be possible to change the handedness with a
matrix transform, if the matrix turns the camera "inside out" much like
"right -x" does.
