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
- Some are related to shape errors when the allowed error to approximate circle
by segment is large and arc radius small.
- fix the actual error used in ConvertToPolyline().
- Use SHAPE_ARC::DefaultAccuracyForPCB() instead of a fixed value as extra margin
in zones. It should not change something, because it is also a fixed value
(5 micrometers), but it is not a magic number.
-TransformArcToPolygon() fix some issues and add a new algo, based on the arc actual
outline shape (initial algo is still available in code, just in case).
Note also the transform is still not good: the same parameters are applied
to convert inner arc, outer arc and middle arc of a thick arc to segments.
But these parameters depend on arc radius (or circle radius) value.
The hittest needs to use distance calc rather than squared distance.
This also adjusts the radius value to be double as to avoid unneeded
loss of precision
The arc shapes need to connect with their adjacent points. By storing
the relevant points, we allow exact point matching on both ends of the
arc as well as localize point storage.
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
* 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.
