Available since LÖVE 0.8.0
This function is not supported in earlier versions.

Returns the meter scale factor.

All coordinates in the physics module are divided by this number, creating a convenient way to draw the objects directly to the screen without the need of graphics transformations.

It is recommended to create shapes no larger than 10 times the scale. This is important beacuse Box2D is tuned to work well with shape sizes from 0.1 to 10 meters.
