tdf#103474 handle quarter angles before using atan2
sin(basegfx::deg2rad(fEAngleDeg)) does not result in 0 for
fEAngleDeg=180 because of rounding errors and therefore
atan2 later in the code gives wrong angle.
Because the corresponding circle angle is the same as the ellipse
angle for 0°, 90°, 180° and 270°, these angles are now handled
before using atan2.
