Two potential differences I see between these icons and what we have
in etc/images are:

  . None of the icons in etc/images has size more than 24x24, while
    the images in idlw-toolbar.el are 28x28;

  . I see no stuff like "s backgroundToolBarColor", only "s None", and
    only in 2 icons in etc/images/

Can you see whether one of these differences is the culprit?
