We now test the midpoint (B) of the 3 consecutive polyline points (A, B, C), since (assuming the angle between AB and BC is > 90 degrees) AC is always longer than
AB or BC. This minimizes the distance computation rounding error (in the previous algorithm, taking the point C for colineraity test) if AB is short and BC is very long, the test would
often fail due to rouding error in projection/line distance computation
We can't know that all holes will be ccw when entering unfracture.
Instead, we set the largest polyline to be the outline and the others to
be the holes.

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.

This also fixes a failure to use the correct effective width for
shapes (which might, for instance, inherit their widths from schematic
defaults, netclasses, etc.).

Inflate with linked holes needs to account for fractured polygons,
otherwise inflating with positive value will create rounded divots where
overlapping fracture lines meet and inflating with negative value will
create spaces between fracture lines.
Calling Simplify before Inflate takes an inordinate amount of time as
the Clipper healing routine is rather slow. Our own Unfracture is meant
to heal the results of our Fracture routine and works much more quickly.
After healing, we still call the Simplify routine
(cherry picked from commit 9ca35cbcee)
Clipper can handle complex input polygons but we will sometimes struggle
dealing with outputs from the inflate routine that have degenerate or
overlapping points. Calling Simplify after the inflate keeps our
polygons easier to handle

(cherry picked from commit a24cdcb3f0)
Since we use center points to move back and forth for angle and
adjustments, we want to ensure that our center point is stable.
Rounding using integers introduces a 0.5 int uncertainty in each
measurement. These are combined together multiple times to calculate
the center point, which combines the uncertainty. Propagating the
uncertainty to the final calculation allows us to assign a range of true
values and pick the value that is most likely the correct value.

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.

Test should not be testing against the polygonization error; if done
correctly that should all be on the correct side of the shape. Use an
epsilon instead (I chose polygonization error / 10, but the value isn't
terribly important).
Fixes https://gitlab.com/kicad/code/kicad/issues/10724
The existing algorithm nicely handled the error being on the inside (where
the segment ends are error-free), but not when it was on the outside (where
the segment midpoints are error-free).
In any case, we want error-free points at each end of the arc so we don't
get ears or divots.
(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.
The arc2segment collision should at also include the arc endpoint projections on the segment being tested. Not sure it covers all possible cases, though.
Fixes: https://gitlab.com/kicad/code/kicad/-/issues/9023
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.
Fixes https://gitlab.com/kicad/code/kicad/-/issues/9670
Boolean Ops on polygons with arcs are not supported (the only exception
is Simplify)
Also fix a bug in SHAPE_LINE_CHAIN::splitArc that resulted in an
exception
Partially fixes https://gitlab.com/kicad/code/kicad/-/issues/9380
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
Fixes https://gitlab.com/kicad/code/kicad/issues/9380
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
Fixes https://gitlab.com/kicad/code/kicad/issues/9362
We are not always sure of the path validity in fracture. Nominally, the
Clipper Simplify routine should remove invalid parts but in the case
where it doesn't, we need to recover gracefully, even if the output
polygon is not valid.
Fixes https://gitlab.com/kicad/code/kicad/issues/9199
- allows setting a minimal seg count for circles and rounded end segments.
- When using ERROR_OUTSIDE, ensure the arc correction is the actual value
needed by the segment count, not the max value allowed
This ensures that the arc shapes remain correct after removing
a point belonging to an arc or inserting a point in the middle
of an arc.
Simplify implementation of Replace( ..., aP ). Now a Remove
operation followed by an Insert operation.
Improve QA test for SHAPE_LINE_CHAIN Append, Insert and Replace
Implement SHAPE_LINE_CHAIN::splitArc to break up an arc into two
Implement SHAPE_ARC::ConstructFromStartEndCenter and add qa test
