! Fixed to prev since new warnings appeared after the change.
Please review this. The stack API in some places expects
'int' while other calls use HB_ISIZ. In this case a value
is formed from ( hb_stackTopOffset() - hb_stackBaseOffset() ),
both HB_ISIZ, which is then passed to hb_stackItemFromBase(),
which expects an int.
What is the best way to correct this?
