graphical ->flash: area=[area],
time=[int]Alert the user of a possible problem by shortly inverting the graphical.
Area specifies the area to be inverted, relative to the graphical<-area
of the graphical itself. Time is the time in milliseconds which the
graphical remains in the inverted time; the time of the total operation
is this time, plus two time the required time to invert the area. The
default time the graphical is inverted is determined by graphical.visual_bell_duration.
See also window->flash, device->flash
and tab->flash.
Normally one should invoke graphical->alert,
which depending on graphical.visual_bell
will either ring the bell or flash the graphical.
