// >> mirror brush (up-down)

// NOTE: Animate this on the canvas, then draw:

// if (x > h/2) {
//   lex.assign( canvas.aa[h-y][x] )
// }



// >> rainbow stardust brush

// Uncheck BG and animate this to brush:

// lex.fg = hue(t)
// lex.char = choice("            ,'.,.','******    ")



// >> noise brushes, works on a black background:

// lex.bg = max(5, yellow(randint(t)))
// lex.opacity = lex.bg == colors.black ? 0 : 1



// >> simple rainbow:

// if (lex.bg != 1) lex.bg = randint(t)
// lex.opacity = lex.bg == colors.black ? 0 : 1



// >> self-erasing:

// if (lex.bg != 1) lex.bg = yellow(randint(t))
// lex.opacity = lex.bg == colors.black ? 0 : 1



// >> cycling rainbow brush

// if (lex.bg != 1) lex.bg = hue( all_color_hue_order.indexOf( color_names[ lex.bg ] ) + 1 )
// lex.opacity = lex.bg == colors.black ? 0 : 1



// >> "stars" brush.. set your brush to paint just the character "#"

// if (lex.char == "#") {
//   lex.fg = hue(randint(15))
//   lex.char = random() > 0.1 ? " " : "+@*.,\"+'*-"[randint(10)]
// }



// >> use fg char to mask mask what you're drawing on the bg

// if (lex.char != "/") { lex.bg = 1 }



// >> sharded glitch brush

// Example: http://asdf.us/z/kksnvs.png 

// Use on a brush:

// lex.bg = t/y/x
// lex.opacity = lex.bg % 1 ? 0 : 1



// >> incremental brush

// Set your brush to be the ^ character, square, about 10x10
// Draw "char" only
// Then animate this shader on the canvas:

// if (lex.char=="^") {
//   lex.bg += 1
//   lex.char = " "
// }
// lex.bg += 1
