[luatex] 'glyphing' for smart font rendering

Dear All,

I've started investigating how hard it is to do real smart font rendering by trying to integrate graphite with luatex (via lua). It's going well, except that I realise that luatex is still treating glyphs as characters. What I mean is that while the node.id for a glyph node is set to a glyph, the char is still interpretted via a cmap as a character rather than taking the dimensions, offsets, etc. from the glyph node itself.

Am I right in assuming that it is intended that once a glyph node is no longer a character node but has become a glyph node, that it really will be interpretted as a glyph and the width will come from the node rather than using font,char everywhere in the backend? If so, do you want help in getting there?

I did try to build luatex but it fell over trying to find ptexenc.h from lib/ptexenc. Is that something that should be checked in?
