There is now a Python program installed to a distro's libexec dir
which will generate assets based on the user's current colorscheme. This is
needed for complete recolouration because of the fact that most of
the GTK2 theme is pixmaps. Currently, recoloration only recolors the things
that are not pixmaps, which leads to stuff like
https://bugsfiles.kde.org/attachment.cgi?id=122870.
This is one part of the solution to fixing bug 412331, but is not the whole
solution.
