Unintuitive behaviour of RandAffine and RandAffined

[MathijsdeBoer]

The default behaviour of RandAffine and RandAffined's scale_range parameter is to add a value of 1.0 to all elements of the argument.

See the documentation:

• scale_range – scaling range with format matching rotate_range. it defines the range to randomly select the scale factor to translate for every spatial dims. A value of 1.0 is added to the result. This allows 0 to correspond to no change (i.e., a scaling of 1.0).

This, while clearly stated in the documentation, does seem a little unintuitive, and it has in fact caught me out, where I was simply passing [0.9, 1.1] to the constructor, causing strange warnings downstream in my random cropping step.

Would it be too disruptive to change this to a scale where a value of 1.0 is no change?
