setScale

Sets the number of world units visible of the viewport for one or both dimensions. Set 0 for one of the dimensions to use a derived value based on the other dimension and the aspect ratio. Negative values are also OK. It is typical to set the scale to the number of pixels visible in the this-> This practice is neither endorsed nor condemned. Note that the while the contents of the viewport will appear to stretch or shrink to match the dimensions of the viewport given by setSize, the number of world units visible will remain constant.
