Media: a shaped corner follows the pointer up and down; the fitted crop is told once

With an aspect, a corner drag sizes the crop by whichever side the pointer
moved further, so a drag straight up or down resizes it too. The upload
tells the host the fitted crop once per file, whether the host keeps it or
not; a host that dropped it had set off a loop of reports. The annotator's
Escape stops only when it lets a chosen mark go.
