Apply the Belt Slicing Transform to Painted Supports and Seams

Browse Source 
Painted support/seam facets, support volumes, seam occlusion, MMU and fuzzy skin painting (top/bottom
and side facets) and the adaptive infill octree used trafo_centered(), or trafo() with a centre-offset
shift, while the layers were sliced with the belt rotation, remap and Z lift; they now share
PrintObject::trafo_sliced().
