Re: Cursor on images not visible

[Richard M. Stallman]

    So how about changing the default value of the property `:margin'
    from 0 to 1?  This is better than fixing all packages (e.g. iimage.el
    and cus-edit.el for button images) and adding `:margin 1' to every
    image specification.

That sounds rather drastic--do we know if it will break anything?
Can you find all the Emacs features that use images, and see
if any of them would have a problem with this change?
