Added two shift variables to increase readability 

The halfShift and fullShift variables are based on the original face ellipse shape. They are the
major and minor axis chord lengths of the two different arcs. The fullShift only gets used in positioning
the lower half of the face, everything else is shifted left/right so works off of the halfShift
since it aligns with the minor axis of the top part of the dog's face, which is the x-direction
