[Xy-pic] Conflict between unicode-math and xypic

Hi Ross and all others,

xypdf indeed uses a \fontdimen parameter: \fontdimen8\textfont3 for the 
default line width. Besides, it relies on other parameters calculated by 
Xy-pic, like \xydashl@ for the dash length and \xydashh@ for the 
separation of multiple strokes.

If unusual math font setups cannot provide these parameters, a patch 
should supply these. If there are better or more future-compatible ways 
of getting the math font parameters, please tell me so that I can adapt 
the methods in xypdf.
