Scaling of Drawables

[WilliamQiufeng]

Is your feature request related to a problem? Please describe.
Currently when a tourney referee spectates >2 people the view gets really messy. It would be nice to have a way to scale playfields down and arrange them in grids (田, 品, ...)

Describe the solution you'd like
It is already implemented in the scrapped animation PR, so all we need to do is pull the relevant code in.

Describe alternatives you've considered
Manually applying scaling under skins would be a nightmare. Can't think of any other good ideas right now.
