[pstricks] change of font and helvetica gridfont

[Patrice MÉGRET]

Dear Herbert,

I came to the same conclusion:  with the package helvet GV searches another Helvetica font than the classical one used inside pstricks.
By way, do you have the same trouble as me with Ghostview?

To solve this trouble, I just use 
\fontfamily{fvs}\selectfont % sans serif Bera Sans     
instead of \fontfamily{phv}\selectfont

and Helvetica is thus not overwritten ==> the ps file is correct.
