redshift (screen colour adjuster)

Redshift adjusts the colour temperature of your screen according to
your surroundings. This may help your eyes if you are working in
front of the screen at night.

This package has a dependency on geoclue2, however it will compile the package
without it if geoclue2 is not present.

This package will build against python3 for the gui if python3 is available.
If not, we use the fedora patch to build the gui with python2. If you want to
compile using python3 on 14.2, you will need the pyxdg and pygobject3-python3
packages from SBo.
