Forgot to mention... or ask.
I guess this come from where the view its positioned.. so If I want to draw anything I will have to do it at .5 on each point, shall I change instead the y origin to a .5 coordinate so I will don't don't put .5 on each drawing I make in the view? or the mistake comes from far more other place?
Thanks
Gustavo
