* | j2k/jpeg2000: split data pointer in int & float.Michael Niedermayer2013-05-30
| | | | | | | | | | | | | | | | | | | | | | | | This fixes a TODO item and unifies both decoders structures It also fixes undefined behavior due to aliasing violations I choose 2 fields instead of a union because mistakely using the wrong type with a union will lead to hard to debug "wrong output" while with 2 fields mistakely using the wrong type will crash with a null pointer derefernce which is much easier to debug Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
