/**
 *   v0.3.2 CHANGELOG ༼ つ ◕_◕ ༽つ
 *
 * - Fixed the coordinate range to be 1,1 - 319,239.
 *
 *   v0.3.1
 *
 * - Updated to the new 3DS layout. Reset your controller settings if the
 *   touch input box is in the wrong location.
 *
 * - The logic has been separated into components for maintainability. There
 *   should be no break in functionality.
 *
 * Enjoy!
 *
 * - Meiguro
