This would normally return the same values the core RandR code passed to xf86RandR12CrtcSetGamma before, which is rather pointless. The only possible exception would be if a driver tried initializing crtc->gamma_red/green/blue to reflect the hardware LUT state on startup, but that can't work correctly if whatever set the LUT before the server started was running at a different depth. Even the pointless round-trip case will no longer work with the following change. Reviewed-by: Keith Packard <keithp@keithp.com>
X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
