-----------
Fix for [#35352] Freestyle + Geometry Spatial Noise freezes on render.

SpatialNoiseShader, as well as SmoothingShader were not updating stroke length after
geometry modification, causing an infinite loop in Stroke::Resample(int iNPoints) due to
incorrect length-based resampling of stroke vertices.
