This requires that the stderr (and stdout) are emptied when the
child process exits, otherwise redshift-gtk will exit before the
error output is forwarded. Also, the '-v' parameter is moved to
the beginning of the command line to avoid error output including
this (e.g. `redshift-gtk -l` would complain about the missing
location provided `-v`).
Implemented through config options transition-high and transition-low (there
is no command line switch at this point). Determines at what solar elevation
Redshift will change from night to transition period to day.

Try to set the process title during startup. Before, redshift-gtk appeared as a python process.
This change enables `pgrep redshift-gtk` or `killall redshift-gtk`.
This allows redshift-gtk to show the current state of the redshift
process. redshift-gtk follows the enable state of redshift and toggles
the icon accordingly.
The implementation is changed to use glib to spawn the child process
instead of relying on python subprocess module. This is necessary
because of inflexibility in the python module.
This was basically a hack that happened to work because the Gnome Clock
applet could store the current location of the user, and Redshift was able
to fetch this location through GConf. Since Redshift for some time now has
supported a config file where the location can be set, there is not really
any reason to use an external, fragile solution to do the same.
This should fix a bug where command line options for the "manual" location
provider cannot override the config file. To keep compatability with previous
versions the command line parser will still special case parsing "-l LAT:LON"
and set the correct options in "manual".
This method does not do anything but print the temperature to the terminal.
An external program implementing a color temperature adjustment scheme that
is not supported by redshift can use this method to determine the desired
color temperature. It is also useful for testing other parts of redshift on
systems where neither RandR nor VidMode works.
This table is calculated by the actual Planckian locus below 5000K, and by CIE daylight standard above 5000K.
Also, the new table applies proper gamma correction according to sRGB.
