Fringe icons have incorrect background and foreground colors in the git
master version of Emacs.
There are 2 issues:
1. The icon is drawn with background color instead of foreground color.
2. The icon background is opaque (and is in foreground color) instead of
being transparent.
I tracked it down to this commit:
67a878f * Honor :fore/background for XBM on NS (Bug#14969).
The attached patch fixes the fringe icon issue for me. I haven't tested it
extensively with other XBM image use case though.
