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.
