In Processing, mouseX and mouseY are always clamped to the sketch window.

In mewnala, they can take values outside the window, all relative to the top-left of the window within the display.

Steps to reproduce

Processing

void setup(){
  size(200,200);
}

void draw(){
  println("mouseX:" + mouseX + " mouseY: " + mouseY);
}

Values stay within [0, width] and [0, height]

mewnala

from mewnala import *

def setup():
    size(200, 200)

def draw():
    print("mouse_x: " + str(mouse_x) + " mouse_y: " + str(mouse_y))

run()

Example output:

mouse_x: -764.0 mouse_y: -279.0
mouse_x: 963.98 mouse_y: 837.98

Expected behavior

mouse_x and mouse_y should be clamped to [0, width] and [0, height] to match Processing.
