dirty region than the real screen change. A similar behavior may happen on other platforms with damage notification support. So it's better to have an individual layer to handle the Differ logic, and remove capturing independent logic out of each ScreenCapturer* implementation. So this change does following things, 1. Update differ_block to handle variable height. differ_block_sse2 has been renamed to differ_vector_sse2. 2. A new ScreenCapturerDifferWrapper implementation to help set DesktopFrame::updated_region(). It uses an underlying ScreenCapturer to do the real capture work, and updates the updated region of DesktopFrame returned from OnCaptureResult function. 3. FakeDesktopCapturer and FakeScreenCapturer to generate controllable DesktopFrame by using DesktopFrameGenerator and DesktopFramePainter. 4. Test ScreenCapturerDifferWrapper by using FakeScreenCapturer. After this change, we can eventually remove all Differ logic from ScreenCapturer* implementations, and fix a potential crash bug in ScreenCapturerLinux class. It wrongly assumes previous_frame() has a same size as current_frame(). https://goo.gl/3nSqOC BUG=633802 TBR=kjellander@webrtc.org Review-Url: https://codereview.webrtc.org/2202443002 Cr-Commit-Position: refs/heads/master@{#14076}
