The background color was just an example, and we probably do not want to
include a new field for every situation.
My first suggestion would be to let the user specify options that apply to
all filters in the graph: if a filter knows an option with that name, it
uses it, if not the option is ignored for this filter (and if an option is
not known by any filter, print a warning).
But there may be drawbacks to that solution.
