Disk is cheaper than brain :-)

doing all the dependency manipulation in sed (*UNTESTED*),
(drop the manual libgtk deps in d/control):

s/(^[^:]*:)/\1 GTK3 | GTK2,/
s/(GTK2)(.*)(libgtk2.0-0 \([^\)]*\))/\3\2/
s/(GTK3)(.*)(libgtk-3-0 \([^\)]*\))/\3\2/


but not doing fancy things is much less fragile ...

branch WIP/split-gtk contains a commit doing the package split and
removing the fragile magic. (There are no breaks+replaces, this is
intended to be introduced with a new upstream release which renames the
moved files.)
