To clamp a channel in GIL you can just say:

T channel;
T clamped = std::min(channel, channel_max_value<T>());

We actually had a set of primitive channel-level algorithms that also
included clamp, but we decided to remove things you can do with a simple
one-line expression so we don't clutter the interface.
