PicoGK v1.3

[LinKayser]

Dear all,

we released PicoGK v1.3 yesterday, which adds a new function to the Voxels class to determine the normal of a point on the surface of a voxel field. I also fixed a number of bugs that affected the quality of the signed distance field when rendering meshes and lattices. These bugs affected the quality of the surfaces of exported meshes slightly in the typical voxel sizes we used in the past (range between 1mm and 0.1mm). But they created substantial artifacts for voxels sizes much smaller or much higher. @josefinelissner discovered them when she was working on a very small object.

The release and release notes are available here.

Happy computational engineering.
