# Shrinking the window past "one row per pane" used to panic: computeGeom gave
# every pane in a column at least one row, so `y` walked off the bottom and
# renderPane got a rect outside the surface (assert). Panes that no longer fit
# now get h = 0 and simply do not render until the window grows back.
