Hi Daniel,
Thanks! for the input. I'm pondering your suggestions about the code
and I'll check in with you and Mitch on IRC in the next couple of
days.

Just because it's a standard, doesn't mean it's right.

I've made progress getting a linear gamma image to display without
posterization in the shadows. I put up a temporary web page with the
modified code and a picture:

The problem at this point is that the image won't display properly

You should bug mitch or me IRC for faster responses :).
Issues with this code:
Don't modify the buffer you got from gimp_pickable_get_buffer
(GIMP_PICKABLE (projection)), it's a live part of the projection.
Adding the buffer to the iterator twice probably doesn't do what you want
it to do.

Hmm, I managed to get past the problem of not linking to lcms2. The
solution was to compile Gimp using MAKEOPTS=-j3
CFLAGS=-Wl,--no-as-needed LDFLAGS=-llcms2 ./autogen.sh . . .
not that I know why that seems to have worked.
On to the next step.

The conversion happens in app/display/gimpdisplayshell-render.c :
gimp_display_shell_render() .
Look for the gegl_buffer_get call that converts to babl_format
(cairo-ARGB32).
It's more complicated that just that because the display filters all expect
sRGB u8 data still, but I suspect the best
