[ft-devel] improvement to full auto-hinter

[Werner LEMBERG]

Folks,


I've fixed a seven-years old bug

  http://savannah.nongnu.org/bugs/?25392

that improves the rendering of long vertical stems in full
auto-hinting mode (i.e., FT_LOAD_FORCE_AUTOHINT).  Attached are
before-after images of NotoSans-Regular.ttf; in general sans-serif
fonts benefit most of this change.

[Note that I have not yet ported this to ttfautohint, since it is a
 bigger issue due to necessary modifications to the created bytecode.]

Please test your fonts and check whether there are any adverse
effects.
