// This is a special TestCase whose purpose is *not* to test the correctness of
// the Pepper APIs.  Instead, this is a simulated Flash plugin, used to place
// the browser window and other UI elements into Flash Fullscreen mode for
// layout, event, focus, etc. testing.  See
// chrome/browser/ui/exclusive_access/
//      flash_fullscreen_interactive_browsertest.cc.
//
// At start, this simulated Flash plugin will enter fullscreen and paint a green
// color fill.  From there, it will respond to mouse clicks or key presses by
// toggling its fill color between red and blue.  The browser test reads these
// color changes to detect the desired behavior.
