Benoit Jacob 9e15a6da2e Fix 4x4 matrix inversion. Applying Euler's trick is more tricky than what "high performance matrix inversion" websites would have you believe. Our 4x4 matrix inversion wasn't numerically stable, because in applying the Euler trick we didn't take the 2x2 block of biggest determinant. As a result, with float, we got relative errors above 1% every 1000 random matrices, and we got completely wrong results every 10000 matrices. ...

Note that this decreases the performance, but we're still significantly faster than the brutal cofactors approach.
