When a PangoLayoutRun has both foreground and background colour properties set,
gnome_print_pango_layout_line() is left in an unstable state following the
rect_filled for the background colour for the run.

One solution is to follow the rect_filled() with a gnome_print_moveto() to
re-establish the current point.
