Plot the Temperature Text.

I Moved the 'plot text' method of the Old Graphics to the new
layout - this one was mostly unchanged as it was already good
as is.

And used the TemperatureProfileItem to also display texts.
This was the first implementation of the new system that uses
*less* code than the original one, wich makes me happy.
