Performance

[domjancik]

Investigate what makes squrs run slow on mobile and slower computer devices.

From my testing it seems like a lot just goes down to the rendering as making the window smaller gets things running smoother. However the separate loops for each squr are likely also not optimal.

On the rendering side, modifying the squr background to be animated using GPU accelerated opacity might be helpful, together with avoiding unneeded rerenders.

It's true however, that the choppy sounds from my struggling S8 are pretty interesting. I've recorded it and will post later.

Similar effect on faster devices can be achieved by opening the developer tools, enabling the device toolbar and choosing mid-tier or low-end mobile to simulate. Coincidentally, this is probably also a good way to develop the performance improvements.
