## Detailed Description

Interface for a Qt3D frame advance service

This is an interface class that should be subclassed by providers of the frame advance service. When used with the Renderer aspect, the aspect needs to be the one providing the ticks depending on the vertical refresh rate. When used with no Renderer aspect, a default tick clock implementation can be used.
