"Applications need to handle device loss.
Device loss occurs when the underlying gpu rendering context becomes unavailable to the application.
The easiest ways to trigger device loss are to hit control+alt+delete on a Windows machine,
or rotate an Android device while running an AIR app whose app descriptor includes <autoOrients>true</autoOrients>.
You may experience device loss after navigating away from an application and then coming back to it.
In all of these cases, the underlying gpu context must be recreated and all your existing gpu resources become invalid.
Event.CONTEXT3D_CREATE will be fired when device loss occurs.
The application should handle this event by re-uploading textures and reconstructing vertex and index buffers.
