     Build data frome for a plot with given data and ... (dots)
     arguments

_U_s_a_g_e:

     build_df(plot, data, aesthetics)

_A_r_g_u_m_e_n_t_s:

    plot: plot object

    data: data frame to use

aesthetics: extra arguments supplied by user that should be used first

_D_e_t_a_i_l_s:

     Depending on the arguments supplied to 'plot_add' we need to
     stitch together a data frame using the defaults from plot$defaults
     where the user hasn't explicitly specified otherwise.

     Arguments in dots are evaluated in the context of 'data' so that
     column names can easily be references.

     Also makes sure that it contains all the columns required to
     correctly place the output into the row+column structure defined
     by the formula, by using 'expand.grid.df' to add in extra columns
     if needed.
