'sudo apt-get build-dep gimp' will get you all dependencies except
gtk-doc-tools package

http://git.gnome.org/browse/gegl/tree/operations/common/motion-blur.c
http://git.gnome.org/browse/gegl/tree/operations/common/pixelise.c

Not verbatim, but close to original ports:

http://git.gnome.org/browse/gegl/tree/operations/common/mirrors.c
http://git.gnome.org/browse/gegl/tree/operations/common/grid.c

Also note that some filters should become meta-operations which means
an operation that simply reuses other operations as building blocks. A
good example of one is unsharp mask:

http://git.gnome.org/browse/gegl/tree/operations/common/unsharp-mask.c

There are no priorities set. You will find it most encouraging porting
filters you care about most :)

On IRC: #gegl at irc.gimp.net
