If an entire font family is condensed or stretched and we match by family name, the default stretch factor of 100 will make the font engine try to synthesize it back to medium stretched font. The existing code is already made to deal with a stretch of 0 that is no longer used. This patch reintroduces 0 stretch to indicate no specific stretch has been requested. Specifically setting stretch to 100 on a QFont will introduce the old behavior. [ChangeLog][QtGui][QFont] The default value of QFont::stretch() is now 0 to indicate any default stretch is acceptable.
