[Insight-users] confirmation of isotropic spacing requirement for levelset filters in ITK

The level set filter evolves a PDE over time. The PDE solver framework does
not take spacing into account.
The few ones that do have a UseImageSpacing ivar. I would recommend using
the ResampleImageFilter to resample your image to isotropic spacing prior to
using any of the level set filters.
