Add automatic random splats on timer.

[DavidHaitch]

I wanted to use this sim as a more passive visualization for a party. To support this, I've added an "auto-splat" mode that adds random splats on a configurable interval.

(Tip: for best results, let the autosplats develop slowly over time, with low density and velocity diffusions.)

This looks great! I'm going to try to incorporate these random autosplats with spotify song tempo

I'm not sure, but won't this recursion trigger a stack overflow over time?
If that's the case, how about using a setInterval instead?

[DavidHaitch]

After a few hours of runtime, I didn't observe any significant slowdown or memory increase. You may be right that this could happen, but I wanted to use a repeated setTimeout to enable the user to change the splat interval after start.

This particular kind of stack-buildup is only an issue if you have asynchronous stack traces enabled (and by extension the debugger open), which can be disabled in chrome:

Thanks, merged your code into webgl-fluid@0.3.8:

npm i webgl-fluid

WebGLFluid(document.querySelector('canvas'), {
  AUTO: true, // Whether to enable auto-splating
  INTERVAL: 3000, // The time (in milliseconds) the timer should delay in between auto-splating
  SPLAT_COUNT: Number.parseInt(Math.random() * 20) + 5, // Set the splats' count
})
