This function is given a ConnectionId and it converts the corresponding BusWire.Wire type to a Connection type, offering an interface between our implementation and Issie.

This function is given a list of ConnectionId and it converts the corresponding BusWire.Wire(s) to a list of Connections, offering an interface between our implementation and Issie.

Get the coordinate fixed in an ASegment. NB - ASegments can't be zero length

Given a segment start and end position, finds the orientation of the segment. Fails if the segment is neither horizontal nor vertical

Given a segment start and end position, finds the orientation of the segment. Returns None if the segment is 0 length

Given a segment start and end position, finds the symbol edge of the segment based on its segment direction if it starts an outgoing wire.

Convert a (possibly legacy) issie Connection stored as a list of vertices to a list of segments

Identifies a segment as wire:index, short enough to read in a log line.

Given the coordinates of two port locations that correspond to the endpoints of a wire, as well as the orientation of the final port this function returns a list of Segment(s). The starting segment will always be from a Right Edge (and so in increasing X direction)

Given the coordinates of two port locations that correspond to the endpoints of a wire, as well as the final port orientation this function returns a list of wire vertices. The starting segment will always be from a Right Edge (and so in increasing X direction) The two positions are where the wire LEAVES each symbol's bounding box, which for nearly every port is the port itself. Where it is not - a Mux2's Sel sits nine units inside the box, because the symbol is drawn as a trapezium and the port is on the sloping side - the caller hands this the point on the box and lengthens the two end nubs afterwards, so that everything here works in the space a wire is actually free to use.

Function used to render a single wire if the display type is jump

The SVG commands drawing one bend of a radial wire: the line along `before` as far as where the corner starts to be rounded off, then the quarter circle of radius `rad` onto `after`.

Function used to render a single wire if the display type is radial

Collapse a wire's absolute segments into the runs between its bends: drop the zero-length segments, which have no shape, and merge whatever is then adjacent and collinear.

Function that will render all of the wires within the model, with the display type being set in Model.Type `highlighted` says what to show picked out for a reason the draw block cannot know - see DrawModelType.Highlighted. It is applied to the render props rather than to the model, so a wire whose highlight changes redraws and the rest are left to React's memoisation.

The bends of a radial wire, each paired with the radius its corner is drawn with. A bend eats `rad` off the end of the run either side of it, so a run with a bend at both ends can give half of itself to each, and one at either end of the wire has a single bend and can give all of itself. The radius is therefore the standard one everywhere except where there is genuinely not the room for it: neighbouring bends never overlap, and a short run is the only thing that squares a corner off.
