[NTG-pdftex] fix_int() corrections

i wonder whether one should feed back the fix_int() clipping corrections into the variables, e. g. like fixed_pk_resolution := fix_int(pdf_pk_resolution, 72, 2400); pdf_pk_resolution = fixed_pk_resolution; {== this line would be new ==} Currently e. g. \pdfpkresolution is copied to an internal fixed_pk_resolution variable which is silently clipped to 72--2400 dpi and isn't accessible. But \pdfpkresolution remains at its original possibly out-of-range value, so one can't rely on it. This would affect about the following variables: \pdfdecimaldigits \pdfpkresolution \pdfimageresolution \pdfgamma \pdfimagegamma \pdfimagehicolor \pdfimageapplygamma Regards, Hartmut
