I'm not sure that making analogs to the existing framework ScaleTypes is applicable here since they combine alignment operations with scaling algorithms. We can take a look at adding additional documentation with diagrams to help showcase the intent.

as I and few devrel folks did we will still try to make analogs mentally. this means it would be nice to explain more of the difference between ScaleType and ScaleFit in the documentation and mention how to write the analogues for all ImageView.ScaleType. we should document somewhere how to achieve CENTER_CROP with our components, otherwise users will try to find this info on stackoverflow

commit 83158eda183d97d536996830d8a22f78fc27326f

    Renamed ScaleFit API and added documentation
    for improved clarity
   
    Relnote: "Renamed ScaleFit to ContentScale
    Moved ContentScale from ui-graphics to ui-core
    module to live in the same module as the Alignment
    API.
    Renamed FillMaxDimension to Crop
    Renamed FillMinDimension to Fit
    Renamed Fit to Inside to better match
    ImageView.ScaleType equivalents
    Added documentation indicating that the combination
    of Crop and Alignment.Center achieves the same result
    as ImageView.ScaleType.CENTER_CROP and Fit
    used with Alignment.Center achieves the same result as
    ImageView.ScaleType.FIT_CENTER
    Inside used with Alignment.Center achieves the same
    result as ImageView.ScaleType.CENTER_INSIDE"
