It seemed "stuck" if the initial voxel size value under the remesh tab
was larger than or equal to the longer side of the bounding plane. It
actually was not stuck, but needed long mouse travels to get into the
range that we were clamping to (behavior from 4221f827cf clamps to
"sane" values on modal that make sense for differently sized meshes).
The "sane" sizes are kept, but this PR makes sure we actually start off
with an `init_voxel_size` that is already based on the clamped minimum/
maximum (so we dont have to mousetravel that far)
