Gmail 4.2 app for Android leaks; shows pinch-to-zoom, swipe support

Similar to what Android users do in maps or browser, you can easily pinch-to-zoom in the mail text or image to view it clearly. The swipe support is also same as we have seen in notification bar; you can simple swipe an email message away to trash or archive now and if you accidentally do this, there is small undo button also present to save from any mishaps.

The swipe functionality will also be configurable, so you set it to archive, delete or just remove the existing label from an email.
