figure <-
clip_path: path*If not @nil,
the graphicals of the figure are only drawn where they are inside this
path, as determined by path<-fill_rule.
The points of the path are in the coordinate system of the graphicals of
the figure, so the clipping region moves, rotates and scales with them
under figure<-transform.
The path itself is not displayed. Clipping affects drawing only:
graphicals that are clipped away still receive events. After modifying
the path, send figure->clip_path
again to redraw the figure.
Defaults: @nil
