V5: Use NEAREST filter when possible
(changed to use determinant funciton and remove debug printf)
Modifies _cairo_matrix_has_unity_scale to return true for 90 degree rotations
by allowing error caused by inaccuracy in trig functions.
This fails after 14 additions of M_PI_2 to itself as a float argument to
cairo_rotate, but the failure is in the detection of the integer translate,
not in the trig components. I believe this is due to the matrix inversion,
which may need similar rounding.
