A vertex represents a 2D point in the image.
The normalized vertex coordinates are between 0 to 1 fractions
relative to the original plane (image, video). E.g. if the plane
(e.g. whole image) would have size 10 x 20 then a point with
normalized coordinates (0.1, 0.3) would be at the position (1,
6) on that plane.
