This is probably the case.  In the Scene2D, "Entity" is the root object.  I
can't use Keys.forwardTo here because Entity (the root is not an Item.  I'm
guessing Keyboard input is handled differently in Qt3D.

I can put a KeyboardDevice and KeyboardHandler inside of the Entity that
contains Scene2D and that seems to work.  But the entity is capturing
keyboard input and there doesn't appear to be a way to forward it to the
qml Item being drawn inside Scene2D.

Without keyboard input, the Scene2D example is incomplete.
