Title: [Wpf] Fix GetCTM by correctly evaluating DrawingContext CurrentTransform

The Value returned by a TransformGroup Appends each successive Transform, even though they are Prepended when rendering. This change evaluates the CTM by Prepending each transform in the collection, as is required. This restores the correct mirror-image figure in Samples.Drawing.Transformation.
