graphical <-
request_compute: any*When not @nil,
indicates that the graphical is in inconsistent state. Used for graphical
objects that require significant computation to determine their area and
visual representation.
When no argument is specified with graphical->request_compute
the variable will be filled with @on.
If a graphical->request_compute
is invoked on a graphical, PCE's graphical kernel will invoke a graphical->compute
on it if the graphical needs to be repainted or one of the dimensions of
the graphical is requested. See graphical<-area,
display->dispatch
and graphical->compute.
