From qt4's pixeltool, on Mac OS X, PNGs are saved correctly, while on
NetBSD-amd64-current colours are shifted.
Stellarium, on the other hand, saves images with shifted colours on both Mac OS
X and NetBSD.
Both systems run the latest qt4 and libpng from PkgSrc.
No, we don't have PNG-related patches for qt4.
