[TIMOB-5391] Android: Image Bitmap Loaded Multiple Times in ImageView

While evaluating bitmap allocation, we discovered that bitmaps are fetched and scaled-down twice for each ImageView, which should not be necessary. We are working to fix that in core code. Reproduce in 1.7.2: * Create a new app with this app.js:

Titanium.UI.setBackgroundColor('#000');
var win = Titanium.UI.createWindow({  
    title:'Test',
    backgroundColor:'#000',
	exitOnClose: true
});

win.add(Ti.UI.createImageView({
	image: "KS_nav_ui.png"
}));

win.open();

* Launch the app from Ti Studio *to an emulator*. * In Ti Studio, down at the console view, turn off the two "Show console when..." options. * Switch to the FastDev Process console. * When the app loads, you'll notice in the FastDev Process console that KS_nav_ui.png is fetched three times. *It should only be fetched twice* -- once for getting bitmap size in order to calculate a sample size, and once to load the whole thing.
