226 // FIXME: this font is used unitialized for now but should be set to
227 // a proportional font. Here is what Georg Baum has to say about it:
229 bibitemWidest() is supposed to find the bibitem with the widest label in the
230 output, because that is needed as an argument of the bibliography
231 environment to determine the correct indentation. To be 100% correct we
232 would need the metrics of the font that is used in the output, but usually
233 we don't have access to these.
234 In practice, any proportional font is probably good enough, since we don't
235 need to know the final with, we only need to know the which label is the
237 Unless there is an easy way to get the metrics of the output font I suggest
238 to use a hardcoded font like "Times" or so.
240 It is very important that the result of this function is the same both with
241 and without GUI. After thinking about this it is clear that no Font
242 metrics should be used here, since these come from the gui. If we can't
243 easily get the LaTeX font metrics we should make our own poor mans font
244 metrics replacement, e.g. by hardcoding the metrics of the standard TeX
