Re: [csswg-drafts] [css-color-hdr] Add mechanism to query HDR headroom (#9306)

On https://lightroom.adobe.com we'll need this to enable meaningful HDR editing, as you really need to know the amount of HDR headroom you're seeing to accurately understand the preview. For example, in the current Lightroom Desktop UI, as well as in the Adobe Camera Raw UI in Photoshop, we display a histogram of the image, along with a white line showing the peak brightness of the current monitor. It's very common to change brightness as you're editing to test different ranges, so having live updates to this during an editing session is needed,

<img width="281" alt="hdr-range" src="https://github.com/w3c/csswg-drafts/assets/48841507/8688fd11-327e-4d3a-9765-bef8cf229987">

It would be very reasonable to require the user to opt-in to this given the privacy implications.
