Use canvas dimensions instead of arbitrary constants for noise() and noiseDetail() doc iterators

[RandomGamingDev]

Increasing access

This would increase the consistency of the code and make the purpose of the code easier to understand for those looking at the docs.

Most appropriate sub-area of p5.js?

• Accessibility
• Color
• Core/Environment/Rendering
• Data
• DOM
• Events
• Image
• IO
• Math
• Typography
• Utilities
• WebGL
• Build process
• Unit testing
• Internationalization
• Friendly errors
• Other (specify if possible)

Feature enhancement details

For instance, this:

function setup() {
  createCanvas(100, 100);

  background(200);

  // Set the noise level and scale.
  let noiseLevel = 255;
  let noiseScale = 0.01;

  // Iterate from top to bottom.
  for (let y = 0; y < 100; y += 1) {
    // Iterate from left to right.
    for (let x = 0; x < 100; x += 1) {
      // Scale the input coordinates.
      let nx = noiseScale * x;
      let ny = noiseScale * y;

      // Compute the noise value.
      let c = noiseLevel * noise(nx, ny);

      // Draw the point.
      stroke(c);
      point(x, y);
    }
  }

  describe('A gray cloudy pattern.');
}

instead of having this:

  // Iterate from top to bottom.
  for (let y = 0; y < 100; y += 1) {
    // Iterate from left to right.
    for (let x = 0; x < 100; x += 1) {

would have this:

  // Iterate from top to bottom.
  for (let y = 0; y < height; y += 1) {
    // Iterate from left to right.
    for (let x = 0; x < width; x += 1) {
