OK.

Did a build from git this morning [5f2a72cb] ( I hope I did it right;
not used to autotools black art) and I still observe the "new" values
for ascender and descender.
In addition I see that if I remove enforcing truetype
interpreter-version 35 I get better glyph shapes again, but the spacing
between glyphs is still broken (too close, see image below) compared to
v35.
Thanks for your support
