cc44089440 New BuildVolume class was created, which detects build volume type (rectangular,
circular, convex, concave) and performs efficient collision detection agains these build
volumes. As of now, collision detection is performed against a convex
hull of a concave build volume for efficency.

GCodeProcessor::Result renamed out of GCodeProcessor to GCodeProcessorResult,
so it could be forward declared.

Plater newly exports BuildVolume, not Bed3D. Bed3D is a rendering class,
while BuildVolume is a purely geometric class.

Reduced usage of global wxGetApp, the Bed3D is passed as a parameter
to View3D/Preview/GLCanvas.

Convex hull code was extracted from Geometry.cpp/hpp to Geometry/ConvexHulll.cpp,hpp.
New test inside_convex_polygon().
New efficent point inside polygon test: Decompose convex hull
to bottom / top parts and use the decomposition to detect point inside
a convex polygon in O(log n). decompose_convex_polygon_top_bottom(),
inside_convex_polygon().

New Circle constructing functions: circle_ransac() and circle_taubin_newton().

New polygon_is_convex() test with unit tests.

3216448bbc PlaceholderParser: implemented round(), digits() and zdigits() macros.
round() rounds to an integer.
This is a popular request, for example #3472

digits(value, num_digits, num_decimals) rounds to num_digits and
	num_decimals, left filled with spaces.
digits(value, num_digits) the same as digits(value, num_digits, 0)
    Neither decimal separator nor any decimals after decimal separator
    are emitted.
zdigits(...) is the same as digits(...) only left filled with zeros.
If the result does not fit num_digits, the result is never trimmed.

7ff76d0768 New ClipperUtils functions: opening(), closing() as an alternative
for offset2() with clear meaning.
New ClipperUtils functions: expand(), shrink() as an alternative
for offset() with clear meaning.
All offset values for the new functions are positive.

Various offsetting ClipperUtils (offset, offset2, offset2_ex) working
over Polygons were marked as unsafe, sometimes producing invalid output
if called for more than one polygon. These functions were reworked
to offset polygons one by one. The new functions working over Polygons
shall work the same way as the old safe ones working over ExPolygons,
but working with Polygons shall be computationally more efficient.

Improvements in FDM support generator:
1) For both grid and snug supports: Don't filter out supports for which
   the contacts are completely reduced by support / object XY separation.
2) Rounding / merging of supports using the closing radius parameter is
   now smoother, it does not produce sharp corners.
3) Snug supports: When calculating support interfaces, expand the projected
   support contact areas to produce wider, printable and more stable interfaces.
4) Don't reduce support interfaces for snug supports for steep overhangs,
   that would normally not need them. Snug supports often produce very
   narrow support interface regions and turning them off makes the support
   interfaces disappear.

8a2a9dba2f Eradicated admesh from TriangleMesh:
TriangleMesh newly only holds indexed_triangle_set and
TriangleMeshStats. TriangleMeshStats contains an excerpt of stl_stats.
TriangleMeshStats are updated when initializing with indexed_triangle_set.

Admesh triangle mesh fixing is newly only used when loading an STL.
AMF / 3MF / OBJ file formats are already indexed triangle sets, thus
they are no more converted to admesh stl_file format, nor fixed
through admesh repair machinery. When importing AMF / 3MF / OBJ files,
volume is calculated and if negative, all faces are flipped. Also
a bounding box and number of open edges is calculated.

Implemented its_number_of_patches(), its_num_open_edges()
Optimized its_split(), its_is_splittable() using a visitor pattern.

Reworked QHull integration into TriangleMesh:
    1) Face normals were not right.
    2) Indexed triangle set is newly emitted instead of duplicating
       vertices for each face.

Fixed cut_mesh(): Orient the triangulated faces correctly.

965c2f2c55 Improved error reporting when importing various configuration files:
1) Slic3r::RuntimeError was replaced with ConfigurationError,
   all exceptions thrown by the configuration layer are derived
   from ConfigurationError.
2) When parsing configuration files, ConfigurationError is catched and
   rethrown extended with the file name being parsed.

0f3cabb5d9 Support for forward compatibility of configurations, user and system
config bundles, project files (3MFs, AMFs). When loading these files,
the caller may decide whether to substitute some of the configuration
values the current PrusaSlicer version does not understand with
some reasonable default value, and whether to report it. If substitution
is disabled, an exception is being thrown as before this commit.
If substitution is enabled, list of substitutions is returned by the
API to be presented to the user. This allows us to introduce for example
new firmware flavor key in PrusaSlicer 2.4 while letting PrusaSlicer
2.3.2 to fall back to some default and to report it to the user.

When slicing from command line, substutions are performed by default
and reported into the console, however substitutions may be either
disabled or made silent with the new "config-compatibility" command
line option.

Substitute enums and bools only.  Allow booleans to be parsed as
    true: "1", "enabled", "on" case insensitive
    false: "0", "disabled", "off" case insensitive
This will allow us in the future for example to switch the draft_shield
boolean to an enum with the following values: "disabled" / "enabled" / "limited".

Added "enum_bitmask.hpp" - support for type safe sets of options.
See for example PresetBundle::load_configbundle(...
LoadConfigBundleAttributes flags) for an example of intended usage.

WIP: GUI for reporting the list of config substitutions needs to be
implemented by @YuSanka.
