WFD_QNX_port_brightness
WFD_QNX_port_brightness
Description
This extension allows you to change the perceived brightness of a port.
Note:
The use of 'brightness' in this extension is inconsistent with the
'brightness' in the bchs extension, where brightness affects the
color, not the way the color is displayed. In other words, pipeline
brightness changes the color in the WFDDestinationQNX when writeback
is enabled, whereas the port brightness doesn't.
