    app: silence warning in gimp_transform_resize_crop()
    
    The crop-to-result and crop-with-aspect transform-boundary
    algorithms seem to consistently fail in some cases, and spit out a
    warning, which can be too verbose if it triggers the debug dialog.
    
    Demote the warning to a g_printerr(), with an eye to just dropping
    these algorithms altogether.
    
    (cherry picked from commit 0103fe2c194e910b78c3c325905608685967340e)
