Edit > Scale element... scales the whole element about its hotspot by a factor picked from x0.5, x1.5, x2, x2.5, x3, x4. Only the factors that leave every terminal on the 10 px folio grid are offered, so wires to a scaled element stay straight. An element whose terminals are off the grid today is offered only the factors that bring them on to it; if none does, the dialog says so and OK is disabled. Drawn parts are scaled with their existing handleUserTransformation(), as the resize handles do. Texts, dynamic text fields and terminals are set directly so that font sizes (whole points, 4 pt minimum), terminal name offsets and line end sizes scale too, which the resize handles do not do. One undo step restores the element. Unlike "Import an element to resize", this needs no external program and works on the element being edited. Grew out of issue #1338.
