Description

The Problem

If your window uses images with gradients, the gradients can appear very blocky.

The Solution

Expose the "setFormat" method of a native Android window, and allow it to be set to PixelFormat.RGBA_8888 or PixelFormat.OPAQUE [default].

You'll need the gradient.png to test it.

   var w = Ti.UI.createWindow({
   	navBarHidden: false,
   	exitOnClose: true,
   	backgroundImage: 'gradient.png',
   	windowPixelFormat: Ti.UI.Android.PIXEL_FORMAT_RGB_565
   });
   
   var v = Ti.UI.createImageView({
   	image: "KS_nav_ui.png"
   });
   
   var b1 = Ti.UI.createButton({
   	title: "RGB_565",
   	bottom: 10,
   	left: 10,
   	width: 100,
   	height: 'auto'
   });
   b1.addEventListener('click', function() {
   	w.windowPixelFormat = Ti.UI.Android.PIXEL_FORMAT_RGB_565;
   });
   
   var b2 = Ti.UI.createButton({
   	title: "RGBA_8888",
   	bottom: 10,
   	right: 10,
   	width: 100,
   	height: 'auto'
   });
   b2.addEventListener('click', function() {
   	w.setWindowPixelFormat(Ti.UI.Android.PIXEL_FORMAT_RGBA_8888);
   });
   
   w.add(v);
   w.add(b1);
   w.add(b2);
   w.open();
