- \em uses one of the font parameters to determine if the font is
- slanted to decide whether to switch to \rm or \it. In the setup
- here we are using a PostScriptized version of LaTeX and the .tfm files,
- which I assume are generated from .afm files, all have that parameter
- set to 0 - hence I add 1sp to it for all the italic PostScript fonts.
- In this way \em will notice that times-roman-italic is a slanted font
- and so switch to times-roman rather than the original behaviour
- of deciding times-roman-italic was unslanted so it emphasised by switching
- to times-romam-italic - i.e. not very emphatic!
