XeTeX follows consequently the settings inside a font to position  
glyphs, pdfTeX can use PostScript operators to manipulate the shape of  
a font's glyphs.

Do they want to violate a font's design or respect it? That's the  
question. (I would like them to want, no question.) The easier part  
might be to perform protrusion, i.e., letting parts of the glyphs  
protrude into the left and right margins. This is likely to come since  
a year ago the OpenType format has received updates. One of them is  
the "opbd" table or feature (a companion of "rand?") which tells the  
text processor how far the glyph can hang outside of the text area to  
create an improved optical look of the margin.
