// About the full-screen ICC correction: in fact I'm considering to
code a full-screen color correction effect for KWin (even though, as I
said, it doesn't seem that it would fully solve my problem). It seems
simple, I only need to write a shader and an effect which would load
it into KWin. It would be very basic i.e. I probably won't be able to
implement "relative colorimetric" shenanigans and so on, but I think
it should work for simple cases.
There is compicc (compiz-icc) that has this implemented, it just creates
a big 3D texture with all colors and looks up colors by texture lookup.
However a 256x256x256x24 bit texture is slightly scary (48 MB?), a
matrix transformation shader should probably be neater.
Also compicc depends on the overcomplicated Oyranos, so I failed to make
it work when I tried it yesterday.
