in most of files, including wx.h is not necessary, when only 2 or 3 wx files must be included.
Moreover, on windows, including wx.h sometimes create compil warnings about
shadowed vars defined in some specific windows headers.
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.

Partititioning small polygons causes excessive partitions when we use a
fixed number of cells per side. Partitioning by size keeps the
partition count limited and speeds the calculations.
Also adds an option to not partition the grid for elements (like 3d
raytracing) that do not need it.

... instead of modifying the argument.
This will make the method usable in python API and will not incur
permormance penalty because named return value optimization (NRVO)
is a thing since C++11.
But even if copy is not elided vector is moved instead of copied.

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.
