Fix re-calculation of the position of circular drawing objects.

Cell-anchored circular drawing objects would get distorted whenever
its bounding rectangle changes, either via insertion / removal of
columns / rows, or changing the row height / column width.

This commit fixes it by differentiating the validation circles, which
needs its own re-calc algorithm, from the normal circular drawing
objects.
