This has been requested by AndreasBühmann, who has also offered valuable help in implementing this. Now, it isfor instance possible to set up different lists for fonts with optical sizes. (TheMinionPro project is trying to do this for the OpenType version of Adobe’s Minion.See http://developer.berlios.de/projects/minionpro/.)Ranges will be stored as triplets of {〈lower bound〉}{〈upper bound〉}{〈list name〉}.For simple sizes, the upper boundary is −1.2931 \def\MT@get@range#1-#2-#3\@nil{%2932 \MT@ifempty{#1}{%2933 \MT@ifempty{#2}{%2934 \let\MT@val\relax2935 }{%2936 \def\MT@lower{0}%2937 \def\MT@val{#2}%2938 \MT@get@size2939 \edef\MT@upper{\MT@val}%2940 }%2941 }{%2942 \def\MT@val{#1}%2943 \MT@get@size2944 \ifx\MT@val\relax \else2945 \edef\MT@lower{\MT@val}%2946 \MT@ifempty{#2}{%2947 \MT@ifempty{#3}%2948 {\def\MT@upper{-1}}%2048 pt is TEX’s maximum font size.2949 {\def\MT@upper{2048}}%
