Re: Customizing the fringe bitmaps

[Richard Stallman]

    Alternatively, I could also introduce a get-fringe-bitmap function and
    use a :get as Per suggested to be able to edit the built-in bitmaps.
    However, that would make it a little harder to edit the bitmap without
    using Customize.  But in any case, get-fringe-bitmap could be useful
    to get a starting point for editing the bitmaps.

    Should I go ahead?

No, please don't implement it that way.  The clean thing to do is make
the value of the actual variables be one of the binary formats already
supported in :image.  Then you can have functions to convert between
that format and ASCII art.

The advantage of this is that the conversion functions can be used in
other contexts too.  The features are more orthogonal and more
coherent.  So please do it this way.
