Newly the PrintObjects own PrintRegions and Print contains references
to PrintRegions owned by PrintObjects, so that a PrintRegion of the same
content is referenced by Print only once.
The refactoring is a WIP to support multi-material painting.
Fixes Solid infill where there should be none #6482
Also the safety offsetting was revised to be enabled only where needed,
the "do safety offset" is now easy to discover by
a new ApplySafetyOffset::Yes enum, and safety offset over union, which
is better done by offset() / offset_ex() has been replaced with
new union_safety_offset() / union_safety_offset_ex() functions, which
better convey their meaning and which could be better optimized than
union() with the safety offset applied.

Thanks @supermerill for pointing out the issue.
1) Removed the already commented-out scaling / unscaling when doing
"safe offsetting"
2) Removed some of the "safe offsetting" at calls where it never was used.
3) Reworked Clipper & ClipperUtils to pass Polygons / ExPolygons / Surfaces
as input parameters without conversion to ClipperLib::Paths. This
should save a lot of memory allocation and copying.
4) Reworked conversions from ClipperLib::Paths & PolyTree to Polygons /
ExPolygons to use the move operator to avoid many unnecessary allocations.
5) Reworked some "union with safe ofsetting" to "offset_ex", which should
be cheaper.
1) Using boost::preprocessor to reduce code duplicities when defining
new configuration values.
2) Implemented static hash() and operator== on StaticPrintConfig derived
classes to support hash tables of instances thereof.
Thus the first_layer_height is no more object specific. That makes
a lot of sense due to the brim calculation being performed over
all layers at once and due to future merging of supports of
different objects at first layer.
2) Because now first_layer_height is print specific, the relative
first layer height derived from the object layer height was partially
disabled: First the relative first layer height is converted to
an absolute value when importing config, second the side text
was changed from "mm or %" to "mm". Still the UI allows entering %.
Both changes may be controversial, let's wait for user feedback.
just M600, reset the internal retract counter, so that a retract
will happen after the firmware returns from M600 to the initial position.
Fixes "Blobs on print after manual color change #6362"
1) Let Clipper use int32_t for representing its coordinates. This
reduces memory and allows to skip conversion between Slic3r Polygon
and Clipper polygon.
2) Disable additional offset before executing the Clipper Offset algorithm.
We don't see any reason for that and it required 64bit Clipper coordinates,
which were disabled with 1).

expanded to a grid (the old way) vs.
snug (like the upstream Slic3r, Cura or Ideamaker).
Snug supports suffered from the degeneracies when merging overhang islands
over a large number of layers when projecting the support towers down.
We borrowed the idea & a bit of code from Cura by simplifying the support
polygons by closing the concave cracks, see the smooth_outward() function
and the MutablePolygon class.
