        !             2: You can say "set isosamples 30,40" now to get different isosampling
        !             3: rates for the first and second dummy variables (x,u resp. y,v). This
        !             4: will affect surface-plots in hidden3d- and nohidden3d-mode. It gets
        !             5: rid of the necessity of having to change samples in hidden3d-mode when
        !             6: you actually want to change the isosamples for the first dummy
        !             7: variable. For people that are lazy and for compatibility you can also
        !             8: type "set isosamples 30". This will set the value to 30 in both
        !             9: directions. For completeness I did the same with "samples". Thus you
        !            10: can say "set samples 50,100" to get different sampling rates for each
        !            11: dummy variable. This only affects surface-plots in nohidden3d-mode.
        !            12: Again, you still can say "set samples 50". This will set both sampling
        !            13: rates to 50. For 2d-plots the first value of samples is used.
