Summary: plcont, coordinate transformation

Initial Comment:
Hi,

It seems that there is a bug in plcont when using f90 binding

Using the same parameters for coordinate transformations compare to plimagefr 
gives a wrong contour.
See example 16:
http://plplot.sourceforge.net/examples.php?demo=16&lbind=F95

I also have a test case attached. data to use it are here:
http://pascal.parois.net/public/data (quite big, sorry)

I need to transform xtrans(i,j) this way to fix it:
xtrans(i,j)= mod(xtrans(i,j)+ytrans(i,j), 2*planerealhalfwidth)

PS: the use of mod causes glitches in the contour, it's not a bug of plplot

security threats, fraudulent activity, and more. Splunk takes this 
data and makes sense of it. IT sense. And common sense.
