Comment (by TimothyBlynJacobs):

 For schemas like the example that have a property in common that is used
 to disambiguate, we could solve this by introducing a keyword that would
 signify that property. But that would really only work for these `switch`
 type schemas.

 A more generic approach might be to do something like this:

 1. Discard schemas that don't match the type.
 2. For objects, find the schema that has the most properties in common.
 3. Find the schema that has the most keywords that validate.

 We can also mandate that each schema in the `oneOf` array has a `title`
 set. That way we can at least give an error message like "x is not a valid
 Rotation or Crop".
