It's probably important to get the theme integration correct here, so
people can adjust the default highlight colours so that they don't clash
with any other custom colours. Also, a different theme may want to draw
markers in some new fancy way, so it might be important to make sure the
marker information is available when the theme draws the scrollbar
background. Alternatively, we could add a new "marker" drawing function
in GtkStyle, but ideally we want to move away from using abstract
drawing methods.
