Capture a photo from camera with doodling and save.

Take a photo and allow doodling over the top with 'pen' using a small selection of colours and pen widths. Draw over the top of the photograph taken with unlimited undo support and a save option to phone memory or send to another intent such as gmail compose or facebook for example. For inspiration take a look at how SnapChat works for this for it's simplicity and GUI ideas. Concept: * Open App. * See live camera view. * Double tap screen or tap an icon to switch between front and back facing cameras. * Tap button to take photograph. * Display editor GUI elements over the top of the photograph to allow selection of pen ink colours and thickness. Including Undo, Save and Send buttons. * User freely able to draw over the top of the photograph with colour and thickness chosen. Once the user has completed their art masterpiece they can save to local phone memory and then choose to send to another intent such as gmail or facebook instead.
