Canvas rendering looks very pixelated on Retina screens

[heartcode]

The loader is not retina ready at the moment, it would be great to make it somewhat responsive and retinafied.

Some ideas:

Agreed. Would be great if this could be fixed somehow.

Hey guys. I was trying to resolve this issue for an hour and after several unsuccessful attempts i found a very funny, but working solution. Instead of playing with canvas width and height, i am trying to scale it:

var cl = new CanvasLoader('analysis_loader'),
    diameter = 44;
cl.setColor('#ffffff');
cl.setShape('spiral');
cl.setDiameter(diameter);
cl.setDensity(149);
cl.setRange(0.6);
cl.setSpeed(1);
cl.setFPS(60);
if (window.devicePixelRatio) {
  cl.setDiameter(diameter * 2);
  $('canvas').css({
    '-webkit-transform': 'scale(0.5)',
    '-webkit-transform-origin': 'top left',
    '-moz-transform': 'scale(0.5)',
    '-moz-transform-origin': 'top left',
    'transform': 'scale(0.5)',
    'transform-origin': 'top left',
  });
};
cl.show();

It works fine in Mac OS X browsers at latest MBPr: Safari, Firefox, Chrome, Yandex.Browser and latest Opera. Also it must be working at iOS retina devices.

I am not sure about windows retina devices, but if anybody have one, please reply to this message with feedback (work/not work).

Hey Robert,
I guess you don't have the time to fix this issue right now. Any way I could help?
