A second take on HDR support with an SDR white point and HDR headroom

Browse source 
This better reflects how HDR content is actually used, e.g. most content is in the SDR range, with specular highlights and bright details beyond the SDR range, in the HDR headroom.

This more closely matches how HDR is handled on Apple platforms, as EDR.

This also greatly simplifies application code which no longer has to think about color scaling. SDR content is rendered at the appropriate brightness automatically, and HDR content is scaled to the correct range for the display HDR headroom.
