1) The highest priority zone that a via/pad collides with "owns" its
connectivity state. Once set, lower priority zones cannot change it --
and in fact, if they would have connected to it are forced not to.
2) The connectivity state goes with the zone fill state, and therefore
must be saved in the file.
3) Display of remove-unconnected's pads is no longer done in GetViewLOD()
(which isn't called for selected items), and is instead done in PCB_PAINTER.
This allows us to draw the full pad in outline mode when a via/pad is
selected which would otherwise only show the hole.
4) Note that in some cases this will still generate DRC errors -- in
particular when a via nearly collides with a higher priority zone it
won't get "owned" by that zone and may therefore have insufficient
clearance if said zone concludes it's unconnected and a subsequent
(lower priority) zone connects to it (causing it to now become flashed).

It might make sense to do that with board and/or schematic items for
hit-testing or something, but it definitely doesn't make any sense for
the drawing sheet border.
Also, when reading in items with a transparent fill, treat them as
unfilled (otherwise we get filled with layer colour in at least PCBNew).
This function convert a text shape to a set of polygons for the 3D viewer.
Texts shapes are a bit special and can generate a lot of small overlapping polygons.
These polygons are now merged before being added to the list of polygons handled
by the 3D viewer draw functions.
Locally merging polygons is usually not efficient but in this case it can speedup
the 3D viewer (up to 10x).
Mainly noticeable for silkscreen layers when the "copper" thickness is shown
When not aligning under mouse cursor, choose the X-most element where X
is top/bottom/left/right. Previous sorting was not correct for two
directions

We only have a single SOLID per pad, so the solid's shape must always
be the flashed shape and then we can do layer-specific flashing tests
internally.

The effective shapes don't work very well in the custom pad or rounded
rectangle cases, and they're somewhat slower in some of the other cases.
