Fix several UI issues.

1. Remove the cross in border_last_picture
2. Remove the gripper in VideoCamera
3. Solve the popup triangle locate in wrong position
4. Remove the top and bottom borders of the preview frame in Camera
5. Rotate the on-screen indicators when orientation changed
6. Add the checking for the flash mode in VideoCamera
