Description

QPalette::Data::resolve_mask contains only color role data (e.g. QPalette::WindowText), it means that all methods that use this mask don't work correct. For example:

1) QPalette::isBrushSet (documentation is also wrong):

QPalette p;
p.setColor(QPalette::Active, QPalette::WindowText, Qt::red);

qDebug() << p.isBrushSet(QPalette::Active, QPalette::WindowText)    // -> true
         << p.isBrushSet(QPalette::Disabled, QPalette::WindowText)  // -> true
         << p.isBrushSet(QPalette::Inactive, QPalette::WindowText); // -> true

2) QPalette::resolve also works wrong in the similar scenario.
