        * libgthumb/image-loader.c (image_loader_set_pixbuf):
        * libgthumb/gth-exif-utils.h:

        Merged RotatonData, GthExifOrientation and GthOrientation into
        GthTransform. The new enum contains all 8 possible
transformations and
        is compatible with the exif orientation values.
        Moved _gdk_pixbuf_transform_exif_orientation from image-loader.h
to
        pixbuf-utils.h and renamed it to _gdk_pixbuf_transform.
        Moved the implementation of the button callbacks in
dlg-jpegtran.c to a
        common function.
        Combined the two parameters rot_type and tran_type of the
function
        dlg_apply_jpegtran into only one parameter.
        Renamed the function update_rotation_from_exif_data in
rotation-utils.h
        to read_orientation_field.
        Rewrote the lossless jpeg transform to perform all types of
        transformations in one pass.
        Rewrote the generic transform to use the _gdk_pixbuf_transform
function.
        Replaced the get_next_value_* functions with one new function
        (get_next_transformation) that supports all 8 transformations.
Added two
        functions to find the rotation and mirror/flip part of a
transformation.
