Hi Juliusz,
Tested with Chinese fonts in Red Hat 7.3, here are the problems I met:
* m and p spacings don't work, get_metrics can finish loading, then xfs
will crash, hasn't called get_glyphs yet.
* c spacing works but some "dirties" blow each characters, following
patch fix it:

bitmap = &face->face->glyph->bitmap;
if(hasMetrics) {
- wd = tgp->metrics.rightSideBearing;
- ht = tgp->metrics.ascent;

+ ht = tgp->metrics.ascent + tgp->metrics.descent;
} else {
wd = bitmap->width;
ht = bitmap->rows;
* above patch will also allow font size changing, otherwise you can only
use default font size.
