Fix severe performance drop while deflating polylines
Underscaled arc tolerance produced very small values so that changes
to this parameter were negligible when scaled internally, hence significant
performance drop (lots of intermediate points inserted in an arc). Now the
performance is mostly the same compared to other types of offsetting
(SQUARE, MITER).
