/** 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"

#define M_TAU (2.0*3.1415926535897932384626433832795)
precision mediump float;

uniform float u_t, u_N, u_width, u_radius;
attribute vec2 a_wh;
varying vec2 v_texcoord;

void main () {
    float w = a_wh.x; /* which "wedge" we're on */
    float h = a_wh.y; /* will be 0 at center of circle and 1 at rim */

(redblobgames updated this block to use premultiplied alpha - http://apoorvaj.io/alpha-compositing-opengl-blending-and-premultiplied-alpha.html)

I can't figure out why points with gl_FragColor = vec4(255, 255, 255, .1); get darker and then lighter when overlaid with increasing density. (note: it should be vec4(1.0, 1.0, 1.0, 0.1) not 0-255 --redblobgames)

I'm using these blending settings:

blend: {
  enable: true,
 func: {

<!--
  I write my site with xhtml extended with my x: tags, then process it into 
  regular html using xsltproc. Here's an example of how I use xslt for sections.
 
  1. Expand x: tags to a standard html tag:
     <x:section> … </x:section> becomes <section> … </section>

  2. Pass attributes down to the html tag:
     <x:section class="example"> … </x:section> 
     becomes <section class="example"> … </section>
