how to change phsyics world scale?

Hi friends
Physics simulation seems slow however framerate is ok, I think thats because of PTM_RATIO. in some engines like game maker studio we can change “Pixels To Meters”, or in Defold we can set physics world sacle from physics settings. how can i change physics world scale in cocos creator? it seems we are looking objects from long distance and object movements are slow. increasing forces values alone is not good solution to make movements faster, for example if i increase gravity value to increase object falling speed after bouncing with ground it’ll have extra vibration and so on…

The force need to divide the PTM_RATIO too, because PhysicsManager consider everything else is in pixel space.

This is really counterintuitive for physical computing, we may refactor the PTM_RATIO calculation in 3.0.
