Support transformation extent method for log scale charts. (#3746)
Support transformation extent method for log scale charts. (#3746)

The recently added isDataFitToDomain() relies on computing the transformed
viewport domain and extent of values. Calling getTransformationExtent()
works on TensorBoard's LinearScale because it extends
Plottable.Scales.Linear, but fails for LogScale which doesn't have the method.

This adds the missing getTransformationExtent() so that LogScale supports
isDataFitToDomain.
