7456+ debugging purposes. The X axis shows PQ input values, the Y axis shows PQ
7457+ output values. The tone-mapping curve is shown in green/yellow. Yellow
7458+ means the brightness has been boosted from the source, dark blue regions
7459+ show where the brightness has been reduced. The extra colored regions and
7460+ lines indicate various monitor limits, as well a reference diagonal
7461+ (neutral tone-mapping) and source scene average brightness information (if
7462+ available). (<tt class="docutils literal"><span class="pre">--vo=gpu-next</span></tt> only)</dd>
