POC - Combining BW Clock and Desktop Launcher to spend less time "Loading..."

Just tried with:

Bangle.drawWidgets = (dw => {
  return function() {
    var t=getTime();dw();print(getTime()-t);
  }
})(Bangle.drawWidgets);

And widclk installed, and when swapping between the normal launcher and anton clock I see only two calls to drawWidgets taking 50ms each, so I think right now the most recent changes are probably 'good enough'.
