Previously, all overlapping polygons (pads and min thickness areas to remove) were
merged.
Drawback: pads attributes are lost. In Gerber this is annoying.
Now the pads are plot as flashed or Regions items, and min thickness areas are added
but shapes are not merged and keep their attributes.
This only tests the InterceptsPositiveX() and InterceptsNegativeX() used
for finding the midpoint of an arc.
Tidy up some of the trigo.h header Doxygen comments.
This implements all existing symbol library object support and the ability
to save and load symbol library files between file formats for round robin
testing.
Creates new substructure for arc management. Existing functions provide
wrapper to use SHAPE_LINE_CHAIN as normal, without arcs while also
permitting the addition of arcs into the chain
- Fix non optimal shape of solid polygons after inflate transform.
- Add a small extra clearance ((2 microns) when creating clearance areas
(especially, convert arc to polygons create small differences)
- Add a small threshold (1 micron) in drc test distances to avoid false positives
- fix a minor issue in TransformOvalToPolygon that created sometimes a not perfect shape
Fixes#3812https://gitlab.com/kicad/code/kicad/issues/3812
The new line collision search uses BBox() to check for colliding
objects. BBox in the SHAPE_LINE_CHAIN did not include width as the
chains were assumed to be zero-width. This is not the case for
PNS::LINE elements.
We mostly don't notice this because DRC checks for SEGMENT collisions
but it becomes obvious/annoying when we cannot place a track for unknown
reasons and the snap-back doesn't take line width into account.

* Split up the thirdparty code into the thirdparty folder (#3637)
* Create a new kimath static library containing all the math functions
This is part of cleaning the build system for #1906.
Use std::unique_ptr to guard against leaking the new'd pointers
in SEXPR lists if there is an exception during parse.
This was noticable during the Sexpr/ParseExceptions unit test.
Fixes: lp:1830209
* https://bugs.launchpad.net/kicad/+bug/1830209
The SEXPR class is a useful general-purpose S-Expression library
class and can (maybe) be used else where. It also should get
test coverage, as even if noone else uses it, it's critical for the
kicad2step exporter.
Also add some test coverage for some kicad2step routines. For now,
they're not useful outside kicad2step, but they are at least a useful
reference for S-Expression parsing.
