Description Sylvain 2018-10-30 12:54:15 UTC 
This is somehow part of this commit https://hg.libsdl.org/SDL_ttf/rev/55157da58804

Vera font comes from http://ftp.gnome.org/pub/GNOME/sources/ttf-bitstream-vera/1.10/
ttf-bitstream-vera-1.10/VeraBd.ttf

It's a bold font (probably the issue stands with many other bold fonts). 
When you try to render it with underline style, the underline is thicker and then goes after the height. So we increase the height.

This new height is not reported by TTF_FontHeight(), because it's done at render time.
It seems better to do it at init time and when style changes.
