It supports various modes of auto focus. Each modes define as the enumerations
of menu type.
V4L2_FOCUS_AUTO_NORMAL,
V4L2_FOCUS_AUTO_MACRO,
V4L2_FOCUS_AUTO_CONTINUOUS,
V4L2_FOCUS_AUTO_FACE_DETECTION,
V4L2_FOCUS_AUTO_RECTANGLE
In the cause of rectangle it needs the 4 kinds of coordinate control ID of
integer type for expression about focus-spot, and each control ID means
similar to the struct v4l2_rect.
V4L2_CID_FOCUS_AUTO_RECTANGLE_LEFT
V4L2_CID_FOCUS_AUTO_RECTANGLE_TOP
V4L2_CID_FOCUS_AUTO_RECTANGLE_WIDTH
V4L2_CID_FOCUS_AUTO_RECTANGLE_HEIGHT
