Face mesh detection concepts

Face mesh info contains two parts:
468 3D points: Each point has a unique ID, ranging from 0 to 467,
associated with a fixed position on the detected face. For each point:
- x and y are pixel coordinates of the detected face.
- z is the depth info scaled to image size, such that z-values are more
negative when the face is closer to the camera. The origin is the average
depth of all 468 points.
Triangle info: This is used to represent a logical triangle surface in the
detected face. Each triangle contains three 3D points. For example, Points
#0, #37, and #164 construct a small triangle area between the nose and
lips.
