[Pkg-urxvt-maintainers] Bug#886384: rxvt-unicode: font issue with FreeType 2.8 and TrueType fonts

[Vincent Lefevre]

Package: rxvt-unicode
Version: 9.22-2
Severity: important

Just like xterm and Emacs, rxvt-unicode has font issues with
FreeType 2.8, which uses different rounding rules for ascender
and descender for TrueType fonts. 2 consequences:
  * The window is taller and wider than expected (which can break
    existing configurations and waste screen space).
  * There sometimes (not always) are blank lines (rows or columns)
    between characters, which is an issue for line-drawing characters.

FreeType developers assume that applications should not use the
rounded values.

This is an important regression.

Note: Contrary to xterm, for which the problem occurs only vertically,
here it occurs both vertically and horizontally.
