Fix T47705: Freestyle line glitch.

The addressed issue is a regression from Blender 2.75, after the internal
switch from double to single precision floating-point numbers in the
Freestyle code base.  Face normal calculations require the higher
precision during the computations, even though the results can be stored
as single precision numbers.
