Hi, Dick!
I'm very glad to see 'width correction' patch merged upstream!
But for some reason, part of the code was not included. Namely the overrided
virtual functions of inherited class PS_PLOTTER.
This typo makes 'width correction' patch quite useless :(. The solution is in
attachment.
Thanks!
Alexander.
