Before a frame is drawn, you can define how the previous frame will be cleared.
The following clear methods are supported:
| Undefined | Nothing will be done to the background before displaying the next image. |
| Leave | Leave the previous graphic image as the next is drawn. |
| Restore background | Redraw the original background color as the current image is drawn. |
| Restore previous | Redraw the previous image as the current image is drawn. |
This setting can be applied to multiple frames at once.
