If part of the downstream png fix is to link against libpng12, then
gimp needs an override BUILDLINK_API_DEPENDS.png so that
USE_ABI_DEPENDS=3Dno has no effect for gimp.

That's fine.  IGNORE_RECOMMENDED=3Dyes (and now USE_ABI_DEPENDS=3Dno) is
not exactly a fully supported option, as it's not guaranteed to work.=20
However, pkgsrc *can* be fixed to make it work where it is currently
broken, if the brokenness is reported.

That is NOT, however, a reason to stop bumping BUILDLINK_ABI_DEPENDS,
as that is required for default-build reproduceability.
