/**
 * Takes a path to an image, then displays it by filling all available space while
 * retaining w/h ratio. This is meant to be a (poor) replacement to the native 
 * image viewer intent on some devices. For example, the nexus-one gallery viewer
 * takes about 11 seconds to start up when using the following:
 * 
 *     Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
 *     intent.setDataAndType(uri, "image/" + extension);
 *     startActivity(intent);
 *     
 * other devices might have their own issues.
 * 
 * We can support zooming/panning later on if it's important to users. 
 * 
 * No attempt is made to check the size of the input image, for now we're trusting
 * the foursquare api is keeping these images < 200kb.
