Bezier Curves

A little investigation into drawing bezier curves, this description was really helpful

Tap/click a point to toggle moving it its a little buggy looking but it should work fine

I used De Casteljau's Algorithm for this, the tl;dr is:

• Pick n control points
• Connect these control points with lines
• Lerp a point across each of these lines to give you n-1 lines along the paths of these points
• Lerp points across those lines
• Do this iteratively until you end up with 1 point, the line this point traces is your curve
