Unlike protcode.tex and pdfcprot, we do not calculate with \lpcoderesp. \rpcode, since this would disallow protrusion factors larger than the characterwidth (since \[lr]pcode’s limit is 1000). Now, the maximum protrusion is 1em ofthe font.The unit is in \MT@count, the desired factor in \@tempb, and the result will bereturned in \@tempcntb.1189 \MT@requires@pdftex3{1190 \def\MT@scale@to@em{%1191 \@tempcntb=\MT@count\relaxFor really huge fonts (100 pt or so), an arithmetic overflow could occur with vanillaTEX.
