No line spacing when using drawline

In analogy with http://forum.espruino.com/conversations/302392/ I coded a "drawString" override that introduces proper line spacing in Strings witch "\n" newlines in it. In this case I have chosen for 5 pixels of space between each line..

Rather new to Espruino so maybe not the best solution, but it works for me.

Hopefully Gordon will come up with a structural solution.

Example code:

// override drawString function to allocate line spacing
g._ds = g.drawString;
g.drawString = function(s,x,y) {
  s=s.toString();
  sa=s.split("\n");
  print(sa);
  spacing=5+g.getFontHeight();
  sa.forEach(function(line){ g._ds(line,x,y); y+=spacing; });      
};

g.clear();
g.setFontVector(20);
g.setColor(1,1,1);
g.drawString("Temp:\nBattery:%\nCharging\nUptime: 0.00\nFreeFlash: \nFreeStor:",0,30);

And the resulting output:
