Zoom to Fit, with a toolbar icon beside the zoom controls

Fits the whole painted sheet in the visible canvas and scrolls it into view,
from the View menu, Ctrl/Cmd+9, or the four-corners button after the zoom
percentage. The ladder gains 25% and 33% at the bottom, so a wide sheet has
somewhere to fit into.

Fit is the one scale that is not on the ladder -- a sheet fits at whatever
scale it fits at -- so zoom_step now takes the first level above or below the
scale in force rather than the neighbour of the nearest rung.

The sheet is measured from item coordinates rather than canvas.bbox(), which
is inflated by the outline stroke: a stroke is the same two pixels at every
zoom, so a bbox divided back to 1:1 reports a slightly smaller sheet the
further in it is zoomed, and fitting an already fitted sheet crept from 288%
to 291% instead of standing still. Anything painted left of or above the
canvas origin is measured from the origin, since no amount of scrolling brings
it into view.
