In Altium, copper polys will be connected automatically to their
associated pads. In KiCad, we need to do the equivalent when parsing,
which is to combine the joining copper into the underlying pad. We also
don't want to treat copper polys as proxy pads without the original
anymore.
They are particularly damaging when our event loop
gets tied up in knots with the log message window
behind a modal window -- thereby locking up KiCad.
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
The EDIT_TOOL is actually 'co-operating' with the SELECTION_TOOL
by putting its tools into the SELECTION_TOOL's menu. This means
the EDIT_TOOL::m_menu is sad and empty inside, and if you show it,
it either doesn't show at all, or a tiny stub is shown.
The default hotkey is Ctrl+L, as this is not bound by
default in the FP or symbol editor, and it is the hotkey
that is used to focus the address bar in web browsers,
which is a similar kind of action.
This splits the tool into two separate tools: by center and
by even gaps. Previously, this was automatically decided, based on
if the items could have any gaps between them. This was unintuitive
as it would appear to arrange by centre point sometimes but not others.
When items aren't all the same width, the results can then be very
different, based only on the starting positions.
The new behaviour is to have a dedicated tool for each, which echos
how graphical programs like Inkscape manage this.
The by-gaps method is then extended to work for overlapping items
(when items overlap, the overlaps are made equal). The logic is
centralised in kimath/geometry, and some QA is added. This should
make it easier to extend to eeschema, for example.
This also (attempts to) address some rounding issues which could
cause minor, but compounding, errors to build up along the list
of items.
Also, fix bugs in the collection filtering - previously items
like markers were filtered out only after the selection size
was used to compute the gaps between items.
(And we already filter all mandatory fields in
pasteFootprintItemsToFootprintEditor() anyway.)
Also, don't nuke a footprint which contains only fields
during a paste.

Zoom-to-selection should only show the elements that we can see, so
avoiding hidden fields in footprints keeps the zoom window appropriately
sized
