skulpt processing translate function

[technisculpt]

Hi,
i don't think the translate function is working as intended, trying to run some code here: http://www.skulpt.org/static/proctest.html

If you hit run on the following code it will work but if you hit run again it will break and require a page refresh:

from processing import *
from math import sin, cos

global angle
angle = 0

def setup():
	size(250, 250)

def draw():
	global angle
	background(220)
	translate(environment.width/2, environment.height/2)
	line(0, 0, 100*cos(angle), 100*sin(angle))
	angle += 0.03
run()

whereas the following code will work repeatedly (doesn't use the translate function):

from processing import *
from math import sin, cos

global angle
angle = 0

def setup():
	size(250, 250)

def draw():
	global angle
	background(220)
	line(environment.width/2, environment.height/2, environment.width/2+100*cos(angle), environment.height/2+100*sin(angle))
	angle += 0.03
run()
