Accoutning for the seam on createAreaForResize for cellX position

I fix the left side resize issues but that broke right side resizes
because I wasn't accounting for the seam and the other functions don't
need to because they don't receive x,y cell position but they receive
pixel position which are already accounted for by simulateSeam.
