\brief Provides a way to have a synchronous function executed each frame.
The QLogicComponent provides a way to perform tasks each frame in
synchronized with the Qt3D backend. This is useful to implement some
aspects of application logic and to prototype functionality that can later
be folded into an additional Qt3D aspect.
For example, the QLogicComponent can be used to animate a property in sync
with the Qt3D engine where a Qt Quick animation element is not perfectly
synchronized and may lead to stutters in some cases.
To execute your own code each frame override the onFrameUpdate function.
