dotCooCoo d1fb8e540c Geometry: a projective map with entries far apart in size keeps its inverse
The inverse holds every cofactor and the determinant as a mantissa and a
power of two, and forms each entry from their quotient. A map such as
diag(1e-300, 1e300, 1e-300), which counts as invertible, now gets its
inverse diag(1e300, 1e-300, 1e300) instead of none.
