Edit > Aligner gains six commands, also in the selection's context menu and the command search: Aligner à gauche, Centrer horizontalement, Aligner à droite, Aligner en haut, Centrer verticalement, Aligner en bas. One undo step; wires follow their symbols. Second stage of discussion #1069, on top of "Aligner sur la grille". Left/right/top/bottom line the edges up on the outermost one. The two centre commands line the items up on the mean of their centres, and a symbol's centre is its origin point, not the middle of its drawing: in the collection, vertical two-terminal symbols almost always have their terminals on the origin's axis, so this puts their wires on one line. A picture is aligned by the picture itself, without its caption (imageRect() becomes public for this). A group (#1070) lines up as one piece: its edges are its members' together, and every member moves by the same amount, so the group keeps its shape; shapes inside a group come along. Each item moves only across the line it is aligned on, and lands on the grid its drag uses, so aligning never takes a symbol off the grid. Two symbols whose edges sit at different distances from their origins cannot both be exactly on the line and on the grid; they end up within half a grid step of it. The commands need two items (Aligner sur la grille still needs one). Locked items stay put and the status bar says so. If nothing moves, no undo step is pushed and the status bar says the selection is already aligned as far as the grid allows. The geometry is in alignment.h, tested by tst_alignment.
