Fixed visualization of G-code in G-code viewer after 07e7e11590
The line end positions were not extracted correctly from G-code
imported into a stand-alone G-code viewer.
flip direction of the infill layer with each interface layer.
Unfortunately the flipping of support interface directions may not work
reliably due to base support layer heights growing at different rate
from the interface layers.
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.
Fixed crash with zero support base spacing.
The bug fix was not correct and it disabled the new "zig-zag" sparse
infill generator, leading to GH issue #7014
Somehow improved missing interface layers for snug supports
by propagating full overhangs when generating interface layers.
Fixed generation of soluble interfaces for support enforcers,
where base support was used for steeper overhangs.
Disabled filtering out thin regions from the lower layer, that will
not be covered by perimeters, thus they are not supporting the current layer.
However this may lead to a situation where regions at the current layer
that are narrow thus not extrudable will generate unnecessary supports.
For example, see GH issue #3094
with their original names. Using weird shorthands makes the code
unreadable for anyone but the original author.
template<class T> using shptr = std::shared_ptr<T>;
template<class T> using uqptr = std::unique_ptr<T>;
template<class T> using wkptr = std::weak_ptr<T>;
There was a bug for more than 4 years, which likely triggers now more
often with the introduction of raft_contact_distance parameter,
which is usually significantly smaller than support_material_contact_distance.
There were no support towers built at the raft for contact layers
below the print_z of the first object layer.
1) Added parsing of 3MF PrusaSlicer generator semantic version
2) For 3MFs generated by >= "2.4.0-alpha1" and < "2.4.0-alpha3",
remove unreferenced vertices on loading. This should shrink the incorrectly
generated 3MFs back.
3) Added check for an empty mesh, which could have crashed PrusaSlicer on 3MF parsing.
This is a regression wrt. PrusaSlicer 2.4.0-alpha1 due to the G-code
processing optimization and parallelization.

Zero support base spacing is newly allowed, switching from
the "support base" infill pattern to rectilinar infill pattern.
Why someone would want to use a solid infill for support base eludes me,
but it is simpler to support it instead of working out some rules on
minimum support base density.
Fixes Support patern spacing set to zero causing crash #6989
so that a mesh with incorrectly oriented faces will not be considered
a manifold.
Added assert for 3D convex hulls constructed by QHull. They shall be
manifold (however sometimes they are not).
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.
stl_stats are newly only accessed by TriangleMesh::stats(),
most of the direct access to TriangleMesh::stl is gone with the exception
of parsing input files (3MF, AMF, obj).
Sometimes Clipper produces a polyline with more than 2 points when
clipping a line with a polygon or a set of polygons. We hope the intermediate
points are collinear with the line, so we may just ignore them.
Exporting G-code on a worker thread did not work correctly as the worker
threads were using user's locale, not "C" locale.
The "C" locale is newly enforced to TBB worker threads by
name_tbb_thread_pool_threads_set_locale()
WIP to G-code export parallelization through pipelining:
Decoupled CoolingBuffer from GCode / GCodeWriter, ready to be
pipelined on a different thread.
WIP to G-code export parallelization through pipelining:
GCodeProcessor is called during the G-code export,
the G-code is no more reopened and re-read, but it is pipelined
from the G-code generator.
GCodeViewer no more parses G-code just to extract line end positions.
Removed start_mapping_gcode_window(), void stop_mapping_gcode_window(),
they are no more needed.
This is a regression to a late PrusaSlicer 2.4.0-alpha0 change

Faster and hopefully more reliable projection of paint-on support
blockers and enforcers on a sliced mesh.
Previous d89f01c717 did not fix it.

1) Activate installed filament or SLA material profile after update_compatible(),
so that the compatiblity and visibility flags of presets are updated.
2) Only activate the first newly installed filament / SLA material profile
if the active printer did not change. This also means that if no filament
profile was active before Wizard was open or it became incompatible with
the newly installed Printer profile, the default filament profile assigned
to the activated Printer is activated preferably, which may or may not
be one of the newly installed filament profiles.
object layer over raft interface:
"first_layer_speed_over_raft", "first_layer_acceleration_over_raft".
Fixes I have a question about the speed of the first layer after the raft. #6623
Fixes Layer After Raft Is Not Considered First Layer! #6166
1) Changed the name of the variable "brim_offset" to "brim_separation"
for clarity.
2) Added legacy conversion after loading an old 3MF that does not define
then new "brim_separation" variable: The "brim_separation" is being
filled in with the "elefant_foot_compensation" value to produce
equal brim separation to the old PrusaSlicer that saved that 3MF file.
The triangle-ray intersection function used a hard coded epsilon,
which did not work for triangle meshes, that were either too small
or too large. Newly the epsilon may be provided to the AABBTreeIndirect
search functions externally and IndexedMesh calculates a suitable
epsilon on demand from an average triangle mesh edge length.
