However, both the DVI viewer and dvips needto find actual fonts. Therefore, expansion will only work if the fonts for differentdegrees of expansion are readily available.Some packages depend on the value of \pdfoutput and will get confused if it ischanged after they have been loaded. These packages are, among others: color,graphics, hyperref, crop, contour, pstricks and, as a matter of course, ifpdf.Instead of testing for each package (that’s not our job), we only say that it wasmicrotype that changed it. This must be sufficient!4180 4181 \def\MT@setup@PDF{%
