INT SCALED and ASTC_SFLOAT are all very different from a sRGB value.
The old names are retained, deprecated, for backwards compatibility.
Document ktxTexture2_Set{OETF,Transfer,Primaries}.

* Clean up that function. * Fix error in texcoord origin related error message.
Update printdfd to handle newly added transfer function.
Document --no-warn-on-color-conversions in --help text.
