Tonemap hdr to sdr when hdr is enabled and when hevc_hdr/av1_hdr is not used.
Support hdr capture with kms cuda.
Mention known issue, capture on intel wayland compressed data glitch.
Add 10 bit record option, h264_10bit, hevc_10bit and av1_10bit.
Rotate cursor texture properly (around top left origin)
