Default transform type

In certain situations the mapping editor sets the type of a transform to a default transform type.

The situations are:

When you create a new transform.
When you add a connection to an existing transform, and the type of the existing transform is invalid in the new context.

In these situations the mapping editor chooses the default transform type by an arbitrary method from a list of all the transform types that are valid for the current context. The current context includes the number of input and output connections and in some cases the data types of the source elements and the target elements.
