[TIMOB-9447] Android: TableView hasChild icon with Galaxy nexus (all xhdpi devices?)

The hasChild property on a Galaxy nexus (res 1280×720) makes for a VERY tiny icon on the right. I think that there is no xhdpi icon for this, and it displays to a MUCH smaller one. the ldpi, mdpi, and hdpi versions all seem to scale appropriate to its size. The galaxy nexus isn't using the hdpi version. It might be using the mdpi. Appcelerator docs also make no mention of this resolution density (xhdpi) in any of its docs. This resolution should also be included / mentioned to take into account the xtra high res density phones. 1. Run this code:

Ti.UI.backgroundColor = "#000000"

var win = Titanium.UI.createWindow({  
    title:'window',
    backgroundColor:'#fff'
});

var aTableView = Ti.UI.createTableView();

var data = [
	{title:'Row 1', hasChild:true, color:'red', header:'First'},
	{title:'Row 2', hasCheck:true, color:'orange'}
];
aTableView.setData(data);

aTableView.addEventListener('click', function(e) {
	alert('title: \'' + e.row.title + '\', section: \'' + e.section.headerTitle + '\', index: ' + e.index);
});

win.add(aTableView);

win.open();
