Re: [ft] Vertical metrics from FT_GlyphRec - possible?

[Brady Duga]

Hi David,

I haven't tried this yet (I was a little wary of using that flag as  
about the only thing the docs say about it is to not use it), but  
will that make the metrics available in the cache somehow? I see that  
advance has both an x and a y - will the y hold the vertical advance?  
Or will the cache return just the vertical advance if that is what I  
request? I guess I can just try for now and see what happens...
