`arrow.fill` support

geom_segment and geom_curve support arrow.fill which allows to set the fill in the arrow head. It is however not supported by geom_edge_* geoms. Would it be in scope?

krassowski commented

It appears to be an omission, because the function drawing key does utilise (non-existing) arrow.fill:

ggraph/R/geom_edge.R

Line 160 in febab71

fill = alpha(params$arrow.fill %||% data$edge_colour
