QA: Add unit test of SHAPE_ARC Test a few "centre-point-angle" cases and add some generic geom code for testing vectors and boxes are within tolerance (since rounding often creeps in). Much of the arc-checking code will be useful to other construction methods (e.g. point-point-point). There are expected failures for the bbox code when the arc passes though, but does not end on, a quadrant point (0, 90, 180, 270). This is due to a defective implementation of SHAPE_ARC::BBox() that does not take into account the quadrant points. This will be fixed as a follow-up.

QA: Add unit test of SHAPE_ARC Test a few "centre-point-angle" cases and add some generic geom code for testing vectors and boxes are within tolerance (since rounding often creeps in). Much of the arc-checking code will be useful to other construction methods (e.g. point-point-point). There are expected failures for the bbox code when the arc passes though, but does not end on, a quadrant point (0, 90, 180, 270). This is due to a defective implementation of SHAPE_ARC::BBox() that does not take into account the quadrant points. This will be fixed as a follow-up.

Remove all debugging output that cannot be disabled. The use of printf, wxLogDebug, and std::err/std::out causes excessive debugging output which makes finding specific debugging messages more difficult than it needs to be. There is still some debugging output in test code that really needs to be moved into a unit test. Add debugging output section to the coding policy regarding debugging output.

Fix errors in arc polygonization and test case. 1) Tests can't expect accuracies around 1 to work. PCBNew defaults to 5000. 2) Tests shouldn't artifically expand tolerance just to match the results. 3) Tests should guarantee that end point is on arc, not just close to it. 4) Standard polygonization of a circle is inside so splitting the error needs to increase radius, not decrease. 5) Special-case first and last points so that they're exact.

SHAPE_ARC: Expose bug introduced by 5813164d1 in tests The angle needs to be added to the start angle. Add tests to cover this: * Check end point is correct * Check midpoints are within tolerance This would have prevented the bug fixed in 5813164d1, as well as the bug fixed in this commit. As well as failed tests, this manifests when routing across Edge.Cuts arcs (unless they happen to start at 0 degrees staritng angle). Expose as expected failure to prove tests catch it. Fix to follow in separate commit.

QA: Add unit test of SHAPE_ARC Test a few "centre-point-angle" cases and add some generic geom code for testing vectors and boxes are within tolerance (since rounding often creeps in). Much of the arc-checking code will be useful to other construction methods (e.g. point-point-point). There are expected failures for the bbox code when the arc passes though, but does not end on, a quadrant point (0, 90, 180, 270). This is due to a defective implementation of SHAPE_ARC::BBox() that does not take into account the quadrant points. This will be fixed as a follow-up.
