Now split (and no re-introduced commented code, sorry for that):
[gegl_buffer_rename.diff]
Patch from Henrik Akesson that renames pset/pget to
gegl_buffer_pixel_set and gegl_buffer_pixel_get in order to improve
readability of code and to conform to gegl coding standards.
* gegl/buffer/gegl-buffer-access.c
* gegl/buffer/gegl-buffer-private.h
[gegl_buffer_refactoring.diff]
Patch from Henrik Akesson that extracts duplicated code from
gegl_buffer_pixel_get and gegl_buffer_pixel_set into the function
gegl_buffer_in_abyss to improve readability of code and
maintainability.
* gegl/buffer/gegl-buffer-access.c
However for the get_rectangle_as_string functionality, I have to
reconsider given that the function returns a string that is used in
the GEGL_NOTE. You are right that g_string_free (string, FALSE)
doesn't free the actual character data, but it cannot as it is used in
the GEGL_NOTE function call. This means that the string has to be
freed later after the GEGL_NOTE call. In the end it just makes a
complicated code, so it's better not adding it.
Thanks,
Henrik
