Created a new version of calculate_max_limits that doesn't have a
graphics_context and returns a plot_info. The code is basically the same
as the old calculate_max_limits, so there's not much to talk about.
The rest of the code is just boilerplate to plug the Profile
code with the axis and model stuff, to be plotted on screen.
