- Fix annotations for gimp_export_options_get_image() to make it
  actually introspectable with the GimpImage being both input and
  output. Even though the logic doesn't change much (the input image may
  be overriden or not), it doesn't matter for introspection because
  images are handled centrally by libgimp and therefore must not be
  freed. Actually deleting the image from the central list of images
  though remains a manual action depending on code logic, not some
  automatic action to be handled by binding engines.
- Add G_GNUC_WARN_UNUSED_RESULT to gimp_export_options_get_image()
  because ignoring the returned value is rarely a good idea (as you
  usually want to delete the image).
- Remove gimp_export_options_new(): we don't need this constructor
  because at this point, the best is to tell plug-in developers to just
  pass NULL everywhere. This leaves us free to create a more useful
  default constructor if needed, in the future. Main description for
  GimpExportOptions has also been updated to say this.
- Add a data_destroy callback for the user data passed in
  gimp_export_procedure_set_capabilities().
- Fixing annotations of 'export_options' object from pdb/pdb.pl: input
  args would actually be (nullable) and would not transfer ownership
  (calling code must still free the object). Return value's ownership on
  the other hand is fully transfered.
- Add C and Python unit testing for GimpExportOptions and
  gimp_export_options_get_image() in particular.
- Fix or improve various details.

Note that I have also considered for a long time changing the signature
of gimp_export_options_get_image() to return a boolean indicating
whether `image` had been replaced (hence needed deletion) or not. This
also meant getting rid of the GimpExportReturn enum. Right now it would
work because there are no third case, but I was considering the future
possibility that for instance we got some impossible conversion for some
future capability. I'm not sure it would ever happen; and for sure, this
is not desirable because it implies an export failure a bit late in the
workflow. But just in case, let's keep the enum return value. It does
not even make the using code that much more complicated (well just a
value comparison instead of a simple boolean test).

(C) 2004-2012 Shawn Kirst <skirst@gmail.com>,
with parts (C) 2003 Arne Reuter <homepage@arnereuter.de> where specified.
==========================================

This is a plugin for GIMP version 2.4.x. It allows you to load and save
images in Direct Draw Surface (DDS) format.

Features
==========================================
* Load/Save DDS files using DXT texture compression
* Automatic mipmap generation on save
* Load mipmaps into separate layers
* Load cube map faces and volume map slices into separate layers
* Cube and volume map saving
* Pixel conversion selection for custom formats (RGBA4, R5G6B5, RGB10A2, etc.)
* Load/save DDS files, optionally using DirectX texture compression (DXT)
* Optional automatic mipmap generation when saving
* Load mipmaps into separate layers
* Load cube map faces and volume map slices into separate layers
* Save cube maps and volume maps with automatic mipmap generation support
* Save image with a custom pixel format
* Non-power-of-two image loading and saving support with automatic mipmap generation support
* Compliant with DirectX 10 compressed formats
    

Installation
==========================================
See the file INSTALL for installation instructions
