pixel- or vector-level drawing in 2D game?

Unity Engine
1

I wanna make 2D game in Unity. There have been some good solutions for 2D sprite sheets, like ex2D and 2DToolKit, but not all 2D effects are sprites. For example, I’m drawing player’s flying track on screen, and the track can be arbitrary continuous curve. To draw this I need pixel-level control, just like on HTML canvas.

What the best practice to draw 2D things procedurally in Unity? Does ex2D or 2DToolKit support it?

Vectrosity would be a good way to draw lines with pixel-level control.
