[Dev-luatex] Varying font names for the same font

Hi, Some font get a prefix that varies from run to run. This happes to LMMono12-Regular LMRoman10-Regular LMRoman12-Bold LMRoman12-Regular LMSans10-Regular LMTypewriter10-Regular The font LMMono12-Regular may end up being called OIQXZH+LMMono12-Regular. The prefix varies from run to run, making it difficult to compare PDFs. I guess that the prefix is meant to make the font name unique, should there be several different instances of the font. Perhaps a sequence number would work just as well. /Lars
