## vue-canvas.js
/** Canvas component

   A generic canvas component that calls a draw function to draw the
   contents, and automatically calls it again when anything the draw
   function depends on changes. Blog entry:
   http://simblob.blogspot.com/2018/03/using-vue-with-canvas.html

   Example:

   <a-canvas width="500" height="200"

## remove-alpha-on-canvas.js
    const imageData = ctx.getImageData(0, 0, canvas.width, canvas.height);
    const pixels = imageData.data;
    for (let i = 3, n = canvas.width * canvas.height * 4; i < n; i += 4) {
        pixels[i] = pixels[i] < 127? 0 : 255
    }
    ctx.putImageData(imageData, 0, 0);
