• Call DrawLine(Vector2 start, Vector2 end) with start and end UV positions to draw. Note start of call i should be equal to end of call i-1 to draw a continuous smooth path.
• Call DrawStraightLine(Vector2 start, Vector2 end) to draw a straight line.
  Note: You will need to call currentDrawing.Apply() manually to copy the texture to the GPU.
• Call DrawBezierCurve(Vector2 start, Vector2 end, Vector2 control) to draw a bezier curve.
