Viewport Ratio not correct when setImageURI is used.

[malacavilla]

I have code such as:

cropView.setImageURI(imageFileUri);
cropView.setViewportRatio(viewportRatioValue);

The only time the TouchManager's setViewport() code is called is when the we set the viewport. However at this state, the bitmap width/height is 0 (because the Bitmap isn't loaded yet), so we get an imageAspect of NaN, making our viewport non-existent.

This is actually not an issue, see now that it is calculating after Bitmap is set.
