Improved accuracy of internal computation.

The improvement is obtained by using high accuracy linear combinations
and by preserving cos/sin as much as possible. This last part is
important in the frequent case of lines along y axis, i.e. when angle is
π/2. We want the cosine to remain 0 and not get about 10^-17.
