[Qt-interest] QPainter::RenderHints

[Jeffery MacEachern]

According to the documentation[1], setting the QPainter::Antialiasing
flag "indicates that the engine should antialias edges of primitives
if possible".  What exactly does "if possible" mean?  How does Qt
determine whether or not it should "take the hint", if you will?
