Make printing in unix work again.

This fixes the instant segfault when attempting to print I reported on
Friday.

The code to fix it follows.....
//
// Unix PSGraphics class, actually records all pointers to all the fonts
// generated by the findFont method. So if we're printing in unix we can't
// delete this font!
//
#if defined(ANY_UNIX)
        if(m_pG->queryProperties(GR_Graphics::DGP_SCREEN))
        {
                delete pFont;
        }
#else
        delete pFont;
#endif

See ugly ifdef in platform independent code, but this was by the easiest
way to fix this. qnx might have to do this too.

Cheers

Martin
