This comes in the form of a command, `screenshot`, which will read /dev/graphics/fb0 (in a manner very similar to adb's framebuffer_service) and write to the specified PNG file. Additionally, dumpstate now accepts a -p flag (mnemonic: "picture" or "png") that, when specified, will cause a screenshot to be captured in the same directory as the bugreport. Future work: invoke `dumpstate -p` when the bugreport keychord is pressed, giving users a convenient way to attach screenshots to bug reports (or simply take screenshots at all without developer tools). Bug: 2216571 (and probably plenty of others) Change-Id: I36afbc55a0308a7bc01112ef39c4c62777efb203
