<event name="brightness" since="2">
<description summary="current brightness state">
This event advertises the output's current brightness value.
The brightness is an integer between 0 and UINT32_MAX. 0 indicates
lowest light level (while still being powered on) and UINT32_MAX
indicates highest light level.
The brightness event is sent immediately when the object is created if
the output supports brightness. This event is also sent when the
brightness changes.
