[Oiio-dev] Should ImageBuf::WrapClamp be clamping to data window?

[Nathan Rusch]

I was looking at the source of `ImageBufImpl::do_wrap` today, and I noticed that `WrapClamp` always clamps the input coordinates using the display window coordinates (`full_x`, `full_y`, `full_width`, `full_height`, etc.).

I always assumed `WrapClamp` would clamp out-of-bounds coordinates to the available image area (i.e. the union of the data and display windows), but is that not the intended behavior?

Thanks,
-Nathan
