gimp/app/display/gimpdisplayshell-title.c
Michael Natterer 0908e53148 app: use the new unit conversion functions 
and get rid of the brainfuck idea that app/ has to use _gimp_unit_foo()
functions, passing a gimp pointer. Instead, simply use the libgimpbase
API all over the place. Should we ever allow more than one gimp instance,
they will simply have to share one unit database.
