//   What this function does:
//      Rasterizes a single Field Of View octant on a grid, similar to the way 
//      field of view / line of sight / shadowcasting is implemented in some 
//      roguelikes.
//      Uses rays to define visible volumes instead of tracing lines from origin 
//      to pixels.

// One of my new favorite React Hook patternms is to create handler
// functions for a custom hook using `React.useMemo` instead of
// `React.useCallback`, like so:

function useBool(initialState = false) {
  const [state, setState] = React.useState(initialState)
  
  // Instead of individual React.useCallbacks gathered into an object
  // Let's memoize the whole object. Then, we can destructure the
  // methods we need in our consuming component.

// The one in that file uses Promise, but that's *wrong*.
// We only used promise as a demo of its API. We'll remove it soon.

// As you can see below, the pure XMLHttpRequest code is just as clean,
// less mysterious for all, more performant, extensible, and actually correct.

// Ignore these externals for now. They're just for illustration
// purposes. I just copy pasted the Js code from
