Scales for point aesthetics
These are various scales that can be applied to point aesthetics, such as
point_color, point_fill, point_size. The individual scales all have the
same usage as existing standard ggplot2 scales, only the name differs.
See scale_vline_color_hue() for specific scales for vline aesthetics
and scale_discrete_manual() for a general discrete scale.
