dotCooCoo 21b4e70150 Shaper: an arrow widget switches a Shaper Group between Face Selection and Construction mode
A Shaper Group had no arrow widget for switching between Face Selection
and Construction mode.

With the Shaper or Selection tool active, a selected Shaper Group, or a
group with one of its faces selected, now shows an arrow beside the
middle of the right side of its source shapes' bounds. A click on it
isolates the source shapes (object.isolate). A second click leaves
isolation with the group selected (object.exitIsolation). The arrow
points right in Face Selection mode and left in Construction mode.

In Construction mode a Shaper click selects an original shape of the
isolated group. Before, it selected the whole group outside the
isolation, and shaper.select with source could pick an original of
another Shaper Group lying above it.
