Nonplanar Squashed into one commit

added nonplanar layers, the definition of those and the projetion to the top most layer of these nonplanar surfaces.

Merged Point3 implementation from platsch here

added simple support of nonplanar extrusions

Added projection of the non infill extrusion paths

Modified GCode generation for nonplanar layers

Optimized Point in triangle test

Fixed bug in triangle generation for 3D display

Added contour following for freeform surfaces

Added nonplanar printable layers for free form surfaces

added additional debug output

added additional debug output

getting nonplanar projection to work

getting nonplanar projection to work

added different nonplanar surfaces to get more than one nonplanar surface in one object

removed TriangleMesh changes

added multiple nonplanar surfaces in a single object

added multiple nonplanar surfaces in a single object

changed structure of nonplanar surfaces and linked them to the actual layer. Top surfaces are back where the slope is greater than max_angle

added max height option

added config options for nonplanar slicing

fixed segfault for objects with thin extrusions

fixed segfault again

removed areas smaller than 20mm2

fixed gcode generation

added collision detection for nonplanar surfaces

removed bottom layer from nonplanar projection

fixed typo and added extrusion angle compensation

corrected movement on new objects and removed timing prints

removed collisions with size < 1.0mm²

removed debug svg output

added debug output why surfaces are unprintable

Builds correctly in 18.04 with tweak

example gcode file, meant for previews

Calculate the triangle surface using floats

Changing mark_neighbor_surfaces() to not be recursive.

merged master back into nonplanar and try to make old build system running again

added files to MANIFEST

fixed some build issues, tests currently fail

add aditional parameter for maximum printed angle

Better Collision detection

fixed issue with boost on 20.04

added config option for minimal surface area of nonplanar surfaces

Update PrintObject.cpp

disable checks when not nessesarry and added hints to disable collision checks to tooltips

Fixed issue with wrongly projected surfaces

rewritten move nonplanar_surfaces_up

removed svg output and fixed

rewritten the collision checking to get a faster and more reliable check.

switched for variable from i to k

3D support in distance_to to fix broken Douglas-Peucker algorithm in nonplanar gcode export

Fix incorrect type conversion of several ExPolygons to Polygons in projection and collision checking of nonplanar layers, leading to excessiv false collisions in some geometries

Fixed issue with the detection of the correct triangle for endpoints

Added ZipArchive correctly to the CMake Files. Don't know if this was really an issue.
See Zip-o-mat#37

Fixed issues with deprecated BOOST_*_ENDIAN
See Zip-o-mat#37 & Zip-o-mat#38

XMake boost::Placeholders::_1 visible

Fixes slic3r#4967

Do not undefine __STRICT_ANSI__

The `__STRICT_ANSI__` macro is defined by the compiler and it's undefined to undefine or redefine it.

Using `-U__STRICT_ANSI__ -std=c++11` is just silly. If you don't want strict mode, don't ask for strict mode. Certainly don't ask for strict mode and then undefined the macro that is defined by strict mode.

The correct solution is `-std=gnu++11` which doesn't define the macro in the first place.

Stop defining _GLIBCXX_USE_C99 (slic3r#4981)

This is an internal macro defined by libstdc++ to record the result of
configure checks done when GCC was built.  Defining (or undefining or
redefining) the macro yourself results in undefined behaviour.

If the system's C library doesn't expose support for C99 or 'long long'
then telling libstdc++ that it does isn't going to work. It will just
mean libstdc++ tries to use features that don't actually exist in the C
library.

In any case, systems that don't support C99 are probably not relevant to
anybody nowadays.

Fixes slic3r#4975

fix-cmake-boost-1-70+ (slic3r#4980)

Use boost/nowide/cstdlib.hpp instead of boost/nowide/cenv.hpp

Patch build to work on Boost 1.73 and older versions as well.

Changed Message to prevent messages/issues

removed merge conflict

Fixed issue with layer heights >1
