 * @name Letters
 * @arialabel Letters and characters on a grey background. All are white except the vowels are pink.
 * @description Letters can be drawn to the screen by loading a font, setting
 * its characteristics and then drawing the letters. This example uses a for
 * loop and unicode reference numbers to automatically fill the canvas with
 * characters in a grid. Vowels are selected and given a specific fill color.
