c9796d15e1 Fix sbix glyph extents 
* The ‘height’ needs to be negated since the API returns “distance from
  top to bottom side”.
* Similarly, the ‘y_offset‘ needs to be added to the height to get the
  ‘y_bearing’, since sbix’s offset is “the point in the glyph relative
  to its lower-left corner which corresponds to the origin” while
  ‘y_bearing’ is the “top side of glyph from origin”.

With these changes the sbix glyph metrics return values similar to other
tables, as they were otherwise unusable.

2bd953ff4f [metrics] Fix weird use of xor 
I believe that was a try to use one approach as fallback to other.  But
felt wrong.  Just believe what's in OS/2 table to be correct.

c184180228 Fix C++20 compile warning on implicit capture of this with '=' default capture (#1833) 
Happens when compiled with -std=c++2a, the fix just makes the captures explicit to resolve the issue. Just adding this in addition to = doesn't work in C++11.

0d425e1eea [ot-font] Optimize rounding 
Part of https://github.com/harfbuzz/harfbuzz/issues/1801

The assumption that compiler optimizes "upem/2" to a shift only
works if upem is unsigned...  Anyway, spoon-feed the compiler.
