Fixes:
* Various special cases around junctions on pins and dragging.
* Some rotations of endpoints resulting in a 45 degree rotate.
* Some cases where it was possible to get a line with neither
endpoint selected, and also substractive unselecting only one of two
selected endpoints unselecting both.
* Use line midpoint for sorting. Start and endpoints aren't
consistent in the order they appear on the X or Y axis. So,
we need to use the midpoint for our position for consistent
sorting when dragging groups of parallel lines where some
have the start and end reversed.
Other:
* Rename TEMP_SELECTED TO SELECTED_BY_DRAG. This is the actual meaning
of the flag, and should reduce confusion as
to when it should be used.
* Move usage of TEMP_SELECTED as an algorithmic mark to CANDIDATE
instead.
* Fix mistaken clearing of START_POINT and ENDPOINT.
* Move endpoint setting and clearing out of narrowSelection, and into
selectPoint and selectMultiple.
* Don't show dangling end warnings on new lines
If a wire intersects more than 2 pins from the same symbol, we don't
trim connections. If the wire intersects exactly two pins from a single
symbol, we remove the wire between the pins.
We avoided doing this before because we didn't have a good metric for
trimming vs. not. But the per-symbol calculation feels like the least
surprising option.

(cherry picked from commit 75a4036e45)
The use of XOR with integers here is needed as MSVC doesn't implement
the use of std::signbit for integers and casting up to double just to
get the signbit feels wrong
Also fixes some plot bugs with arcs.
Also moves polygonization of arcs (when required) in plotting code
from 5 degrees to calculated based on ARC_HIGH_DEF.

This makes undo/redo look really strange as the other elements get
aligned but the wires do not (or rather their unconnected ends do not)

Keeps the lines connected but doesn't solve the crossed-wire mixups.
This allows common usage (mirroring labels/rotating segments) and leaves
prevention of the crossed wires to the user.
We can't really prevent crossed wires when rotating e.g. a part with
wires connected to 4 sides and users will not expect that. But we
should not disable useful features like mirroring multiple parallel
items to avoid a known impossible situation
Also provides an alternative solution to 345f506f0c that allows us to
rotate groups without destroying connections on hover

We've been doing this for some time to wires that are attached to
the moving block (and therefore have the other end anchored). However
we also need to apply it when dragging a single end of a wire.

We kept having various issues of the pointer list going stale. This
will prevent all permutations of that.
Also while I was in there I fixed the double-move thing (see bug
number).
