I don't know how many users of windows use gplt.  I've encountered 
problems where wgnuplot.exe doesn't die and starts taking up all 
resources on the machine until it is manually killed and so I don't use 
it on Windows.  I would not be sad to see it not included. 

It does provide surface plots, but I would rather see that done with MayaVi.
