Instead of hardcoding the function signature, the better and more general solution is to allow the compiler to do the required overload resolution itself, also allowing for implicit conversions to take place.

Previous attempts to fix it by compensating the trailing space width all failed in some cases, one of the trickiest is when we are having embedded LTR text that has trailing spaces in a RTL paragraph. In this patch we leave line.length not including the trailing space length, but saving it to a separated variable, so that we can always add it back when needed (QTextLine::textLength() for instance). It fixed all the problems in different alignments of both RTL and LTR text. And no regression is found yet.

QPixmapCache has until now refused to throw out shared pixmaps, i.e. ones that still have shallow copies lying around. This leads to problems when someone inserts two shallow copies using different keys, causing the cache itself containing multiple shallow copies and thus forever refusing to throw out those entries. It's rather easy for this to accidentally happen in a user application since QPixmap::load() or QPixmap(const QString &fileName, ...) automatically cache the pixmap in the QPixmapCache, thus if the user then calls QPixmapCache::insert() on the same pixmap or a shallow copy it is locked in the QPixmapCache forever. The only reason for not throwing out a pixmap that's shared would be to prevent re-loading a pixmap from file when a user has a direct reference to it in his application, but in that case the user is unlikely to re-load the pixmap from file in any case. Therefore it seems the best fix is to get rid of this limitation.
