// To do list:
// - improve performance at higher resolutions by drawing the pixel grid using WEBGL (https://npm.io/package/pixel-grid, https://stackoverflow.com/questions/31892414/draw-each-pixel-separately-webgl, https://pixijs.com/)
// - highlight corresponding color in color palete when hovering on pixel, and inverse
// - stroke width control, replace cursor by square of corresponding size and pos when hovering on canvas
// - layers
// - "pixel perfect" drawing tool (smooth curves)
// - striaght line tool, toggleable tools selection panel on lower right, use line tool logic to fill gaps when free drawing
// - cut tool (keep part of matrix)
// - fill tool (change all neighboring pixels of same value at once)
// - rect tool, circle tool
// - select -> copy/cut -> move tool
// - hue shifting, somehow
// - turn buttons & palette into objects of their respective classes, better for referencing each button (instead of using label)
// - add GUI scaling controls (linearly move uipx inside a fixed range)
// - optimize cursor hover checks
// Global variables
// Inner logic
