[Po Lu]

branch: master
commit dd83db2e23062642ab964bad226146a8bdac1349
Author: Po Lu <luangruo@yahoo.com>

    Correct implementations of FLIPRGON and FLIPRGOFF
    
    * src/sfnt.c (sfnt_interpret_fliprgoff)
    (sfnt_interpret_fliprgon): Reorder arguments to match
    the order in which arguments are popped by macro wrappers.
    Fix sundry typos.
