Title: Fix for issue #9865:  Put a tighter range on values for sizeRatio parameter of Quadrilateral function

Put a tighter range on values for sizeRatio parameter of Quadrilateral function to fix issue #9865.

Previously sizeRatio had possible values of 0.5 or 1.5; now the range is 0.5, 0.6, ..., 0.9, 1.0.

sizeRatio values at 1.5 were causing this issue.
