[TIMOB-6392] Android: Ti.UI.Button text values with too many displayable characters draw improperly

Ti.UI.Button text values containing too many displayable characters are: truncated without a visual cue (Android 2.3), displayed outside the background image of the button (Android 2.2, 2.3), or cut in half horizontally (Nook). Screenshots attached. In contrast, large text values in iOS buttons contain an ellipsis (ensuring the user is aware of the missing text). Steps to Reproduce: 1. Create a project using the following code:

Titanium.UI.setBackgroundColor('#000');
var win = Titanium.UI.createWindow({title:'Tab 1',backgroundColor:'#fff'});
var button = Titanium.UI.createButton({title:'Set active tab via index (Controls)',top:160,height:40,width:200});
win.add(button);
win.open();

2. Run the project using the Android Emulator 2.2 WVGA854 (a known error-observable configuration). 3. The button appears. Expected Result: Button text should display within the button area, be displayed in full, or displayed with an ellipsis (i.e., iOS). Actual Result: Button text is displayed outside the button area, horizontally cut in half, or truncated without a visual cue. Note: The Android runtime (V8, Rhino), TiMob SDK, or device orientation do not affect this behavior.
