Square Pixelation

Since the other pixelation shaders I’ve seen have the “pixels” take on the aspect ratio of the image, here is a sqaure pixelation shader. Please don’t put pixel_size too high or Godot will crash, thanks.

Shader code
shader_type canvas_item;

uniform int pixel_size : hint_range(1, 100) = 1;

void fragment(){
	vec2 pos = UV / TEXTURE_PIXEL_SIZE;
	vec2 square = vec2(float(pixel_size), float(pixel_size));
	vec2 top_left = floor(pos / square) * square;
	vec4 total = vec4(0., 0., 0., 0.);
	for (int x = int(top_left.x); x < int(top_left.x) + pixel_size; x++){
		for (int y = int(top_left.y); y < int(top_left.y) + pixel_size; y++){
			total += texture(TEXTURE, vec2(float(x), float(y)) * TEXTURE_PIXEL_SIZE);
		}
	}
	COLOR = total / float(pixel_size * pixel_size);
}
