This helper method is used to set the inset position cache at drawing time. However this is already done by the drawing code itself (MathRow::draw, RowPainter::paintInset), so that there is no need to do this same work again in a different place. Note that the inset positions are still set in InsetTabular::draw for each cell. This commit comes with a mild risk attached (it might be that some of these calls were useful after all!), but all of this is fixable.
