Geom-ggproto.RdAll geom_ functions (like geom_point) return a layer that contains a Geom
object (like GeomPoint). The Geom object is responsible for rendering the data in the plot.
Each of the Geom objects is a ggproto object,
descended from the top-level Geom, and each implements various methods and fields.
Compared to Stat and Position, Geom is a little different
because the execution of the setup and compute functions is split up.
setup_data runs before position adjustments, and draw_layer
is not run until render time, much later. This means there is no setup_params
because it's hard to communicate the changes.
