/**
* 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.
