Jean-Marc Lasgouttes 21422dd652 Replace QFontMetrics::width() by horizontalAdvance() in Qt>=5.11
The method horizontalAdvance() replaces width() starting with Qt 5.11.
To handle this, all direct calls to QFontMetrics::width() are replaced
by calls to GuiFontMetrics::width(), and the code for
GuiFontMetrics::width(QChar) uses horizontalAdvance on newer Qt
versions.
