Zoom and pan the preview with the wheel, and step a parameter from its ruler

Cursor over the image: the wheel zooms about the pointer, and a drag pans,
both clamped to the contain-fit of the loaded bitmap so the photo can never
be lost off-screen. Cursor over an open parameter ruler: the wheel moves that
parameter by one step, clamped to its min/max. While the crop frame is being
dragged the wheel keeps resizing the crop instead, and APPLY puts the view
back on the fit.
