As far as I know, the returned value is currently set to 0x00, but you can check that easily.
I did some work to be able choose this behavior, but it's not ended yet. This work in the abyss branch in git. More details here: https://mail.gnome.org/archives/gegl-developer-list/2011-October/msg00003.html
If you would like to complete this work, please go ahead.

Hello all,
In GIMP,the area-filter-operations always get more pixel data out of the input buffer's extent, then output the processed data.
So, how the pixel datas out of extent are gotten in gegl-buffer-set and gegl-buffer-get ,maybe they are all set 0x00, or another setting method??
such as:
gegl_buffer_get(input_buffer, 1.0, src_rect, format, in_data,GEGL_AUTO_ROWSTRIDE);
if src_rect is larger than input_buffer->extent ,what data will be stored in in_data? What is the machanism?
Now our progress is slow ,because of the problem. So,can anyone help us explain it?
We're so glad to receive any advice from you!
Thanks a lot!
