Re: [Devel] Kerning problem with capitals

It's a completely different problem.  The applied kerning is
completely correct, and the result is still bad.  This is a font
design issue of Vera.ttf, and FreeType can't solve that problem.

Actually, it is.  Except kerning, there is *no* interaction between
glyph images.

Given that today most kerning data is in GPOS tables, a higher-level
library is needed to interpret the layout context.

I've explicitly added a code example to the documention which shows
how to use lsb_delta and rsb_delta.  You might contribute code to,
say, either the Pango or the ICU project so that autohinted fonts get
proper handling.

I don't understand what you are talking about!  Where is the
connection between binary compatibility and bad kerning?
