+Overview of changes leading to 1.2.4

+====================================
+
+- Synthesize GDEF glyph class for any glyph that does not have one in GDEF.
+ I really hope we don't discover broken fonts that shape badly with this
+ change.
+- Misc build and other minor fixes.
+- API changes:
+ - Added HB_NDEBUG. It's fine for production systems to define this to
+ disable high-overhead debugging checks. However, I also reduced the
+ overhead of those checks, so it's a non-issue right now. You can
+ forget it. Just not defining anything at all is fine.
