// One of QML's limitations that is making it difficult to integrate
// the two languages at the moment is the fact that, given:
// main.qml: MyItem { id: myItem }
// MyItem.qml: CppItem { property int myProp; Rectangle { id: myRect } }
// doing qmlContext(myItem) from C++ will return the QQmlContext of main.qml,
// which won't allow us to access properties and IDs defined in MyItem.qml if
// we want to place the C++ implementation as the root item.
// Having the C++ implementation as the root of components would make passing
// whole components between QML and C++ implementations much simpler and would
// allow us to define more properties in C++.
// For now we'll place our C++ implementation as a child item of MyItem.qml
// to be able to get the right QQmlContext, and we'll rely on the fact that
// our C++ implementation is intantiated as an "impl" property of its component's root.
