maybe also add hz support for ttf fonts

(currently limited to type1; why?)

The hz algorithm changes the FontMatrix of the font. The FontMatrix is a property of a Type1 font. If you want to do it in a more general way you have to change the PDF text matrix. But though this had been done in dvipdfm, it's not easy. BTW., for the same reason ExtendFont and SlantFont do not work with TTF. Changing the text matrix would be better because currently a font is included more than once if font expansion is used. There is another nasty thing: CFF fonts can have a single font with different font matrices, but there is a restriction in the PDF spec which allows only one FontMatrix for a particular CFF font. Changing the text matrix would have a few advantages: * The file size will be significantly smaller. This did not matter in the past because very few people used font expansion, but with the advent of \autoexpand and microtype.sty it will affect many files now. * ExtendFont and SlantFont will work with TTF fonts as well. * If dvi output is required, pdftex can insert a \special which changes PostScript's matrix in a similar way as it does it for pdf output. This will not work for TTF in dvips, though. Hans, you are the second one who asked (I asked Thanh a few years ago), so I think that the priority is not very high. I think that it should be put on a TODO list. I also recommend to look into Mark Wick's sources. He already solved this problem. What is needed to make dvips able to process TTF? If no subsetting is required, will dvips be able to deal with Type42? Type42 can be created from TTF on-the-fly. Is it difficult to insert the pdftex TTF subsetting code into dvips? It is useful to care about dvi output and dvips because many people ask how to use psfrag and using dvips -E and epstopdf is a simple solution.
