Revert "Compare to epsilon instead of 0 in CFX_Matrix::SetReverse"
This reverts commit fbd9ea1db2f1bb7fa006e7304a1202afc683c142.
Reason for revert: This check seems too strict
BUG=chromium:714187
Original change's description:
> Compare to epsilon instead of 0 in CFX_Matrix::SetReverse
>
> Since we are going to divide i by 0, it is better to compare it to epsilon
> and avoid wonkiness from division by something too close to 0.
