Move 'plot_info' into 'struct graphics_context'

Browse source 
.. and then allocate just the plot-info entry array dynamically.

structure, because we want to do computer selection and maximum
time/depth/temperature computations *before* we start plotting anything,
and before we allocate the plot entry array.
