<description summary="set HDR metadata for a surface">
Forward HDR metadata from Vulkan to the compositor.
HDR Metadata Infoframe as per CTA 861.G spec.
This is expected to match exactly with the spec.
display_primary_*:
Color Primaries of the Data.
Specifies X and Y coordinates.
These are coded as unsigned 16-bit values in units of
0.00002, where 0x0000 represents zero and 0xC350
represents 1.0000.
white_point_*:
White Point of Colorspace Data.
Specifies X and Y coordinates.
These are coded as unsigned 16-bit values in units of
0.00002, where 0x0000 represents zero and 0xC350
represents 1.0000.
max_display_mastering_luminance:
Max Mastering Display Luminance.
This value is coded as an unsigned 16-bit value in units of 1 cd/m2,
where 0x0001 represents 1 cd/m2 and 0xFFFF represents 65535 cd/m2.
max_display_mastering_luminance:
Min Mastering Display Luminance.
This value is coded as an unsigned 16-bit value in units of
0.0001 cd/m2, where 0x0001 represents 0.0001 cd/m2 and 0xFFFF
represents 6.5535 cd/m2.
max_cll:
Max Content Light Level.
This value is coded as an unsigned 16-bit value in units of 1 cd/m2,
where 0x0001 represents 1 cd/m2 and 0xFFFF represents 65535 cd/m2.
max_fall:
Max Frame Average Light Level.
This value is coded as an unsigned 16-bit value in units of 1 cd/m2,
where 0x0001 represents 1 cd/m2 and 0xFFFF represents 65535 cd/m2.
