Don't fork off a new GIMPX project.

GIMP uses a plug-in system to read/write files. You can easily write
support for a new file format by creating a plug-in for it.

Use any existing plug-in's source code as an example:
http://git.gnome.org/browse/gimp/tree/plug-ins/common/

Plug-ins for PPM, TGA, RAW (raw data, not camera RAW photos), XPM, etc. 
are rather simple and can be a good foundation to start a new plug-in.

If you don't need a GUI, you could also try using GEGL for image
processing which will give you more precision. GEGL also supports
plug-ins, which are called operations in its nomenclature.
