Physics stage 2: colliders gain the shapes capsule and polygon, a polygon keeps its corners in the property points, turns, scales and mirrors with its object and is edited in the scene view (drag a corner, click an edge to insert one, double-click to delete, at least three stay, each step one undo step), a concave polygon is split into convex parts, a self-intersecting one is drawn red and collides with nothing, Rapier gets a capsule and one convex collider per part on the same body, and Move and the editor run use our own f64 geometry for the new shapes, where on a tie between two normals the one that blocks the move least wins, so a box no longer stops at the foot of a slope (#151); first version of a collision outline per texture frame, edited in the texture tab with the new Collision toggle, which a plain tile blocks with instead of its rectangle (#141, to be reworked)
