- override
Returns the distance from the y-coordinate of the position of the box to the y-coordinate of the first given baseline in the box's contents, if any, or null otherwise.
Do not call this function directly. Instead, call getDistanceToBaseline
if you need to know the baseline of a child from an invocation of
performLayout or paint and call getDistanceToActualBaseline if you
are implementing computeDistanceToActualBaseline and need to defer to a
child.
Subclasses should override this method to supply the distances to their baselines.
