We cache arc data to ensure that we know if it has changed since
loading, however footprints perform transformation (displacement +
rotation) on their internal elements, so we need to provide the same
transformation to the cache in order to assure it matches when writing
to disk, otherwise, the arc midpoint will be recalculated leading to
instability

Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
Currently, the system allows custom color selection for the Fill Color
property in the Properties toolbar even when Fill Mode is set to Body
Background Color via the Properties window. However, this does not update
the color to match the Body Background color. To fix this, custom color
selection for Fill Color will be disabled when Body Background Color is
chosen.

There was a gentle mish-mash of booleans, some with
true being left/right and some up/down, and some functions that
can flip in both axes (which is never actually done, and doesn't
really make geometric sense).
Replace all this with the FLIP_DIRECTION enum class, which makes
the intention completely unambiguous.
This also then allows a small scattering of simplifications,
because everything takes the same type and you don't have to
fiddle booleans to fit.
Beziers can extend outside the control point hull,
and can also be far inside the hull. Especially the latter
interferes with selection.
So use the approximated segments to determine.
For some obscure reason, the end points of segments were swapped.
Note graphic RECTANGLE shapes have still an issue when flipped, but this
is a very different issue.
Add direct handling of quadratic beziers to save compute time and number
of points. Update cubic interpolation to reduce number of points
generated for a given smoothness
Cache data on open and used cached data to avoid multiple re-calcs
Remove minimum line length and number of segments and replace with
standard max error level. Allows us to specify the tolerance of bezier
interpolation
Added Distance(VECTOR2) function that returns a double. Removed
superfluous EuclideanNorm, GetLineLength, integer constructor for
EDA_ANGLE (this promotes to double in the CTOR), DistanceLinePoint and
HitTestPoints
Also extended the size for arc calculations that get distances to center
points to avoid overflow
Also fixes some bugs with property exposure that (along with
other things) allowed you to put table cells on a different
layer than their parent table.

IPC2581 is a modern production file exchange system. It provides
single-file data output for an entire board including BOM and netlist
information.
