The upcoming Cocoa port will be supporting video filters. Most of the video filters do out-of-bounds memory reads, but Nearest+ 1.5 is special in that it uses a macro for its pointer arithmetic. 64-bit Mac OS X isn't as forgiving as other OSes when it comes to this stuff by throwing SIGSEGV faults. This patch works around the issue by expanding the offending macro and explicitly performing the pointer arithmetic.

    This is probably not mac os x specific so what about fixing the macro for everyone and possibily move the code out of windows/ if will be used by other ports? Zeromus?

    Sorry, I only test my patches against OS X and Windows, so I don't know what the effects would be on anything else. That's why I made the #ifdef OS X specific.
