For unknown reasons, Clipper2 only returns Paths structures from the
ClipperOffset::Execute routine. Further, the Paths are not properly
ordered (outline->hole in outline, outline2->hole in outline2).
To get proper hierarchy, we need to run an additional pass of the
solution with the paths as Subject in a null union. This is effectively
a Simplify() call but we keep the data in Clipper format to reduce the
churn/calc time
In Clipper1, we had a flat tree structure on returns. Clipper2 nests
these, so we need to properly handle the nesting structure when
importing the polygons
Currently this lives behind the advanced config flag `UseClipper2`.
Enabling this flag will route all Clipper-based calls through the
Clipper2 library instead of the older Clipper. The changes should be
mostly transparent.
Of note, Clipper2 does not utilize the `STRICTLY_SIMPLE` flag because
clipper1 did not actually guarantee a strictly simple polygon.
Currently we ignore this flag but we may decide to run strictly-simple
operations through a second NULL union to simplify the results as much
as possible.
Additionally, the inflation options are slightly different. We cannot
choose the fallback miter. The fallback miter is always square. This
only affects the CHAMFER_ACUTE_CORNERS option in inflate, which does not
appear to be used.
Lastly, we currently utilize the 64-bit integer coordinates for
calculations. This appears to still be faster than 32-bit calculations
in Clipper1 on a modern x86 system. This may not be the case for older
systems, particularly 32-bit systems.
Oh dear, there was a bunch going on here. Firstly the move from int
to long long int for ValueFromString() means that we were no longer
catching overflows (as we were C-style casting it back to int in many
places). But even when the overflow is caught, it would run in to
wxWidgets' empty string bug while trying to log it.

The hash table for integer hashes is extremely limited and places most
elements in the same buckets. This leads to a linear search time for
structures built on this.
This blocks hashes, directing the coder to utilize std::set or std::map
structures instead of hash tables for implementing integer-based
lookups.
1) Move a bunch of std::map's to std::unordered_map to get constant-time
look-ups
2) Lengthen progress-reporting intervals to spend more time doing work
and less time talking about it
3) Reverse order of SHAPE_LINE_CHAINs in thermal intersection checks to
make (much) better use of bbox caches
4) Don't re-generate bboxes we already have
5) Fix some autos that weren't by reference (and were therefore copying
large datasets)
6) Rename delta progressDelta so it's easier to search for in future
7) Get rid of a few more autos (because I don't like them)
8) Pass large items to lambdas by reference

Placing via in walkaround mode and colliding with an arc triggered an
unneeded assertion.
Also fixes the bad assertion format that did not receive strings
(cherry picked from commit df9cf0a0c3)
In addition to showing resolved clearance, we also show the calculated
clearance in the same method as is used for DRC. This will allow users
to better examine their system while working.

The fractional part of Altium schematic units is an integer number of
1/10000 mil segments, which is 2.54 nm. The internal unit of eeschema
is 10 nm, so each fractional unit in Altium is 0.254 base eeschema
units. To be consistent with
cf33cfcad1
we round to the nearest 10nm for each element

Mainly CacheTriangulation() was creating triangles using partition mode.
But this mode is optimized for Pcbnew and Gerbview and different internal units.
Now CacheTriangulation() is used in no partition, much faster in GERBVIEW_PAINTER.

1) Generate SHAPE_POLY_SET triangulation by outline so they can be
shared between connectivity system and other clients.
2) Don't add items to connectivity when reading board; we're going
to do a total rebuild anyway.
3) Use multithreading when caching triangulation.
Handles checking output of the arc to ensure we don't end up generating
an invalid arc. Also keeps the limit of the arc angle to be (360,360)
excluding 0.
Fixes https://gitlab.com/kicad/code/kicad/issues/10070
(cherry picked from commit 8fc831cbc2)
(Conversion was upside-down.)
Also fixes bugs with rotation angle increment not getting units
set and with a 0 footprint editor value overwriting a non-zero
pcb editor value (or vice versa).
Includes bug fix for catastrophic error in Add() for converting to
radians.
Includes bug fixes for the fact that the pcbnew test can't seem to
find the ANGLE_* objects (getting all 0's instead).
1) Unify metrics between stroke and outline fonts
2) Unify handling of rotation and mirroring
3) Bug fixes in collision handling
4) Use of VECTOR2I (instead of VECTOR2D) for world-coordinates
5) Generate outline font overbar with rounded ends and fix rotation
bugs
6) Generate wxEVT_CHOICE events from FONT_CHOICE::SetFontSelection
7) Change text-item PNS SOLIDs to use compound shapes
This one is primarily about pushing TEXT_ATTRIBUTES in to the GAL
API, but it also includes adding EDA_ANGLE signatures to some trig
routines to ease integration.
ADDED arc, circle and rectangle shapes for schematic. Shapes support
line styles and fill colors.
CHANGED sheet background color in Edit Text & Graphics Properties to
fill color (and it now affects shapes).
Pushed STROKE_PARAMS down into common and moved all shapes to using it
for stroke descriptions.
Clipper might mess up the rotation of the indices such that an arc can be split between
the end point and wrap around to the start point. Detect if this happened and fix it as
required.
Also, handle arcs at the last segment of the chain correctly, meaning we can have arcs
towards the end of the chain that finish at the starting point of the chain.

If the last three points of a tesselation are concave, we will never be
able to triangulate them. They were likely formed from a bad polygon,
so we will drop the triangle and return completed

Changes a dot to be a square pixel (linewidth x linewidth). This allows
the removal of IU dependencies and ensures that a dot is always visible
on screen. Also makes sure that cairo is setting the current linewidth
during its stroke routines
