Create zResolution property #1

3D Printers don't have infinite Resolution on the Z-Axis. So we can round the Pixel height to the nearest multiple of our Printers Resolution.

e.g. if our Printer can print layers of 0.1mm in height, it makes no sense for us to create Pixels at a height of 0.553. we should round this to 0.6.

A positive sideeffekt of this optimization is, that we can reduce a lot more Points because more Points share the same layer.
