I wanted to give the caching code in FreeType a whirl (seemed like a
better idea then writing my own), but I am having some trouble
figuring out how to get all the data I need out of it. Originally, I
was just loading every glyph I needed when I needed it. I would
render it if I was drawing, otherwise I would just load it to get its
metrics. In that scenario, I would use the metrics exposed by the
glyph slot, which has vertical metrics when they are available in the
font. That all works, but when I look at using the cache, I see I get
back a glyph, not a glyph slot. The glyph itself does not seem to
have vertical metrics. Specifically, there is no vertical advance,
just a generic "advance" which seems to correspond to the horizontal.
Is there a way to get the vertical metrics as well? Or should I load
(but not render) the glyph to get the metrics, then grab the bitmap
from the cache when I want render the text?
