A little late now, but you should at least bump minor;  This breaks
code for swscale users who previously passed in int values (like, oh,

We ran into the problem because we wanted to disguise the PixelFormat
dependency in other objects and hence pass-around an opaque int; we
just didn't cast it when passing back into SWSContext calls because we
didn't have to (until this morning when our builds started breaking).

It's a simple fix in users' code, but I think it is an API change
(yes, for the better, but a change none the less).
