You can draw something inside a node using the callbacks ```onDrawForeground``` and ```onDrawBackground```. The only difference is that onDrawForeground gets called in Live Mode and onDrawBackground not.
You do not have to worry about the coordinates system, [0,0] is the top-left corner of the node content area (not the title).
Both functions receive the (Canvas2D rendering context)[https://developer.mozilla.org/es/docs/Web/API/CanvasRenderingContext2D] and the LGraphCanvas instance where the node is being rendered.
You do not have to worry about the coordinates system, (0,0) is the top-left corner of the node content area (not the title).
```js
node.onDrawForeground = function(canvas, ctx)
node.onDrawForeground = function(ctx, graphcanvas)
