Returns a ggplot object showing the accumulated cost surface with isolines
and origin location(s), or the isolines alone
(type = "contour"), reproducing the two output types of
movecost <= 2.x's outp parameter - but on demand, without re-running
the analysis.

)A ggplot object (draw it by printing; customise it with +).
a movecost_accum object.
"raster" (default; accumulated surface, slope-shade, isolines) or "contour" (isolines only).
TRUE (default) or FALSE: label the isolines.
transparency of the slope-shade overlay (0.5 by default).
size of the isoline labels (2.5 by default, in ggplot2 text-size units).
colour of the isolines and their labels (default
"white", which reads clearly against the dark low-cost core of the
viridis "C" palette; over the "contour" output, where there is no
coloured background, "grey20" is used automatically unless the user
overrides iso.col).
line width of the isolines (0.3 by default).
unused.
