Hello! Would like to ask support for HDR to be implemented. I'm helping test aqueous which does 10-bit HDR and when I try to use grabit with HDR enabled I get

[error] wlr-screencopy: compositor advertised no supported shm format (want XRGB8888/ARGB8888/XBGR8888/ABGR8888/BGR888/RGB888, saw unknown)

It appears to work! Certainly no error after I set capture.hdr = true. Aqueous dev set up a patch to get it working for screenshot utilities that don't do HDR, so I'm not 100% sure. Waiting on a response from them.

Edit: yea we good!
