screenshots are taken using ISurfaceComposer::captureScreen() which returns the size of the screenshot and an IMemoryHeap containing the data. screenshots have limitations: - they will always fail if a secure window is up on screen - require GL_OES_framebuffer_object extension - in some situation, video planes won't been captured Change-Id: I741c68a2d2984fb139039301c3349e6780e2cd58
