No. With Mitch's help I did made a patch file (which might be out of date by now, as Gimp keeps changing): http://ninedegreesbelow.com/temp/gimp-lcms-deprecated.html#patch > * Change the lcms-based conversion (modules/display-filter-lcms.c) > from being a generic display filter to be something that takes a > GeglBuffer in and blits into a cairo_surface_t. > * Change the display filter interface to accept a GeglBuffer instead > of a cairo_surface_t.

Your suggestions sound very helpful. When I started looking at Gimp color management I had no idea how very complicated Gimp code is. The light began to dawn as I tracked down the functions that are involved in sending image data to the monitor. Then I traced the function calls from the time Gimp is started until main.c hands control over to Glib (g_main_loop_run). Glib? I have a sense of how Gimp and Gegl, and Gimp and Babl, interact. Would some kind soul be willing to provide a quick overview of the relationship between Gimp and Glib? And between Gimp and Cairo? I realize that Cairo sends the image data to the screen, but what is the advantage of using Cairo?
