/**
 * Prior to version 20, If the Layout specifies extra space between lines (either by spacingmult
 * or spacingadd) the StaticLayout would erroneously add this space after the last line as well.
 * This bug was fixed in version 20. This method calculates the extra space and reduces the height
 * by that amount.
 *
 * @param layout The layout.
 * @return The height of the layout.
