       Without going into detail of how these functions, work, we can assume that
       vec2 is always a 2D position [x,y] and vec4 is always a color [r,g,b,a].
       So in short, the vec2 functions are related to geometry, whereas the vec4
-      functions are related to color. To illustrate that, we can compare the
