label: "area:" vs. "area2"
-------------------------------------------
keyboard equiv: <none>

This entry has two different states, "area:"
(read area file in entry into .origarea field),
and "area2" (read area file into .origarea2).

On startup, the default state is "area:", which
is used to (re-)read ("R" button) vertexwise
area, used when reporting the area of labels (or
during F3 interface shrink operations).

Clicking on the label "area:" (bold to indicate
it is button-like) swaps in the "area2" label,
which changes the function of the "R" button to
read the area file instead into the .origarea2
field.  The .origarea2 field can be used for
calculating area ratios.

Clicking the label again toggles it back to
"area:"

See the "area:" line "D" button help for how to
automatically generate an area ratio display
(either current area divided by original area, or
area file divided by area2 file).
