        * app/core/core-enums.h:
        * app/core/gimpimage-scale.[ch]: Added the GimpImageScaleCheckType
        enum and used it in gimp_image_scale_check() which used to be
        gimp_image_check_scaling().

        * app/gui/image_commands.c: Used the above when checking
        scaling parameters to display a message if the image is too big
        or too small after scaling. Closes bug #21028.
