This is a board file format change to account for the new properties.
Also, we now only store the critical information about the dimension's
geometry in the board, rather than storing every drawn line.
The DIMENSION object is now an abstract base, and ALIGNED_DIMENSION
is the implementation that exists today (we will add more dimension
types in the future)
1) For a while now we've been using a calculated seg count from a given
maxError, and a correction factor to push the radius out so that all
the error is outside the arc/circle. However, the second calculation
(which pre-dates the first) is pretty much just the inverse of the first
(and yields nothing more than maxError back). This is particularly
sub-optimal given the cost of trig functions.
2) There are a lot of old optimizations to reduce segcounts in certain
situations, someting that our error-based calculation compensates for
anyway. (Smaller radii need fewer segments to meet the maxError
condition.) But perhaps more importantly we now surface maxError in the
UI and we don't really want to call it "Max deviation except when it's
not".
3) We were also clamping the segCount twice: once in the calculation
routine and once in most of it's callers. Furthermore, the caller
clamping was inconsistent (both in being done and in the clamping
value). We now clamp only in the calculation routine.
4) There's no reason to use the correction factors in the 3Dviewer;
it's just a visualization and whether the polygonization error is
inside or outside the shape isn't really material.
5) The arc-correction-disabling stuff (used for solder mask layer) was
somewhat fragile in that it depended on the caller to turn it back on
afterwards. It's now only exposed as a RAII object which automatically
cleans up when it goes out of scope.
6) There were also bugs in a couple of the polygonization routines where
we'd accumulate round-off error in adding up the segments and end up with
an overly long last segment (which of course would voilate the error
max). This was the cause of the linked bug and also some issues with vias
that we had fudged in the past with extra clearance.

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.
Str2Double assumes current locale. We usually switch the locale when
reading files but we should be using the function that explicitly gets
the C-locale conversion.
Eagle includes stroke thickness into font size, KiCAD does not. Remove
the hack with scaling down the font, compute size precisely.
CHANGED: Fixed font calculation in Eagle import
Eagle cutout polygons only restrict filled copper, they do not limit
tracks, vias and pads inside them. Fix this behavior in the Eagle
import.
CHANGED: Fix semantics of Eagle cutout polygons
Commit d7272b7f5e fixed the use of
the eagle DRC to change the library pad shapes. This was also
applied incorrectly to SMD stacks.
Remove the references to m_rules in packageSMD() and the code
that deals with them. eagle 7.7 does not have any SMD pad options
other than rectangle with rounding.
* 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.
Eagle includes the width of the polygon line when generating polygon pad
sizes where KiCad does not. This simple fix inflates polygon pads half
of the Eagle polygon line width.

We need to set the footprint local coordinates of the footprint
reference and value fields at instantiation separately from the
TEXT_DIVERS elements.

(cherry picked from commit a43a228f78)
This places the arc approximation setting in the kicad_pcb file and uses
it for all parts of the board rendering where arcs are converted to
segments. This allows the user to customize their speed vs. accuracy
tradeoff. The default setting of maximum error of 0.005mm is acceptable
for small boards on moderate systems.
