We do not have a real ScreenCapturer test before. And after CL 2210443002, a new ScreenDrawer interface is added to the code base to draw various shapes on the screen. This change is to use ScreenDrawer to test ScreenCapturer. Besides test cases, some other changes are included, 1. A WaitForPendingPaintings() function in ScreenDrawer, to wait for a ScreenDrawer to finish all the pending draws. This function now only sleeps 50 milliseconds on X11 and 100 milliseconds on Windows. 2. A Color structure to help handle a big-endian or little-endian safe color and provide functions to compare with DesktopFrame::data(). Both ScreenDrawer and DesktopFrameGenerator (in change 2202443002) can use this class to create colors and compare with or paint to a DesktopFrame. 3. ScreenDrawer now uses Color structure instead of uint32_t. BUG=314516 TBR=kjellander@chromium.org Review-Url: https://codereview.webrtc.org/2268093002 Cr-Commit-Position: refs/heads/master@{#14058}
