SPE-2202: Reimplementation of the projection algorithm of painted mesh on slices inside multi-material segmentation.

Browse Source 
This new implementation should resolve several types of artifacts with multi-material segmentation.
It should also increase the precision of projection, so sliced models should be much closer to how they were painted.

Also, the slicing of painted models should be faster than before.
