[luatex] From glyph node to font to glyph width

[Yannis Haralambous]

Could you please tell me how to access the font of a glyph?

When traversing a horizontal node list I get nodes of type glyph, if t  
is such a node then t.font gives me an identifier. How do I get the  
font with that identifier?
I have tried font[t.font] but it didn't worked. The goal is to obtain  
the TeX dimensions of the glyph.

thanks in advance

Yannis
