I like New_Core's use of a single loop to get two coordinates; I think this is a slight improvement on that aspect.

u/donbright

this stuff would be much cooler if i had a faster machine i think
u/Purpzie

are you saying that WE COULD HAVE DONE c.width|= ON ITS OWN LINE THIS WHOLE TIME INSTEAD OF c.width
u/Purpzie

*c.width|=0
u/magna

That's effectively c.width|=x.stroke()
