Dimitar Asenov 3270b4490b Add a new optimization flag to QGraphicsItem. ... The new flag ItemContainsChildrenInShape is similar to the existing flag ItemClipsChildrenToShape. Setting the new flag makes QGraphicsScene assume that children are drawn within the shape of the current item but this is not enforced by clipping. When an application manually ensures this clipping boundary, setting the new flag removes the overhead of enforcing the clip with ItemClipsChildrenToShape, while still allowing other routines to behave more optimially by assuming children are within the shape of the current item. [ChangeLog][QtWidgets][QGraphicsItem] Added the ItemContainsChildrenInShape flag that enables using optimizations of ItemClipsChildrenToShape without the overhead of enforcing the clip.
