[bug#55769] [PATCH] gnu: Add xwhite.

[derekchuank]

I've fixed all the issues you mentioned: adopt meson build system, add GPTv2-only license in README, fix return values in code and a new description. Again, Thank you very much for your detailed guidance and patience.

+   (description "@command{xwhite} is a command line tool for adjusting the colour

+balance of screen.  It is based on xrandr's gamma correction and brightness adjustment.

+As such, it can only be used for X displays and not Wayland displays.  It is typically

+used for tuning the color balance and color temperature.  It has a similar function as

+@command{redshift -P -g R:G:B -O temperature}, but @command{xwhite} is more flexible

+in that it does not keep the white color fixed, suitable for setting the white color

+to an arbitrary balanced color.")
