This may or may not be helpful, but back in commit b87400c78b04, I added 
the ability to specify the particular bitmap to use for a fringe icon. 
For example, you can set 'bookmark-fringe-mark' to any known fringe 
bitmap, and then you'll see that bitmap in the fringe for your 
bookmarks. In essence, this lets you split the semantic meaning for a 
fringe marker ("this marker means there's a bookmark here") from the 
actual bitmap data ("what it looks like").

There's probably room to expand this convention from bookmarks to other 
parts of Emacs, and maybe Flymake could benefit from it.
