* sRGB space. Values outside the range 0.0 - 1.0 can encode
* color outside the sRGB gamut.
* Used to blend / merge multiple dataspaces on a single display.
* Extended range can be used in combination with FP16 to communicate scRGB or with
* SurfaceControl's setExtendedRangeBrightness(SurfaceControl, float, float)
* to indicate an HDR range.
*
* When used with floating point pixel formats and #STANDARD_BT709 then [0.0 - 1.0] is the
* standard sRGB space and values outside the range [0.0 - 1.0] can encode
* color outside the sRGB gamut. [-0.5, 7.5] is the standard scRGB range.
* Used to blend/merge multiple dataspaces on a single display.
*
* As of Android U in combination with composer3's mixed SDR/HDR feature then this may
* be combined with SurfaceControl's setExtendedRangeBrightness(SurfaceControl, float, float)
* and other formats such as RGBA_8888 or RGBA_1010102 to communicate a variable HDR
* brightness range, which in turn will influence that layer's dimming ratio when composited
