    Description

      Hello, I have found an issue. If I split a QPainterPath into two parts through Boolean operations, there will be two paths.Then draw the two paths, the result effect hava a drity line through the cross edge, but Illustrator does not have this problem. I feel that the SourceOver mode did not consider source alpha plus destionation alpha. If SourceOver is not a problem, should qt design a new composite mode?
