ScreenCapturer tests may fail on trybot, so this change is to fix the issue. Changes include, 1. Sometimes, a capturer may capture part of the change, i.e. usually the draw actions are not atomic. So the updated_region may be inaccurate. So I have added a MayDrawIncompleteShapes() function in ScreenDrawer. If it returns false, the updated_region check will be ignored. 2. Several test cases may run concurrently, which makes one ScreenDrawer won't really work. Its window may be covered by another ScreenDrawer. So I have added a system wide lock to ensure only one ScreenDrawer is working at a certain time. 3. On unity (Linux), the top several pixels of a window may be covered by a shadow effect if the window is not focused. So I have added a BringToFront() function, and call it in WaitForPendingDraws(). 4. On Windows, the drawn shapes are 'temporary drawing', which will be erased once the window is covered by another one. So I repeat DrawRectangle() function call in the test case. TODO(zijiehe): The DISABLED_ prefixes will be added back after the code review. And I will move these test cases into modules_test in a coming change.
