In this case, the issue is not about a deprecated api, but two
implementations where one of them is deprecated.
I was told that libswscale is supposed to be a replacement for
img_resample.c, and (most) application have already been ported. However
since it is not a drop-in replacement (it does introduce a different
API, so real porting efford is needed), provding both implementations
enables distributions to support legacy, unported applications as well.
