Fixed issues with the touch coordinates in landscape mode.

In landscape mode the frame stays the same, and the transform property is modified with the appropriate rotation.
The touch coordinates are rotated by the transform, so if I want to normalize them by the frame rect, I have to transform the frame rect first.
