Summary0002117: Support reading display profile using XICC
DescriptionWith the proposed XICC scheme, a colour profile for a display can be set on the display as an atom. Support reading this and offering it as an option in the profile selection list (named "System Display Profile" or something), probably the default until/unless the user chooses something else.

#ifdef QT_WS_X11

#include <X11/Xlib.h>
#include <X11/Xatom.h>
#include <lcms.h>


static KisProfileSP KisProfile::getScreenProfile (int screen)
#ifdef QT_WS_X11

        Display *dpy;
        Atom icc_atom, type;
        int format;
        long nitems;
        long bytes_after;
        unsigned char *str;
        int result;

        cmsHPROFILE *profile = NULL;

        static Atom icc_atom = XInternAtom( qt_xdisplay(), "_ICC_PROFILE", False );

        if  ( XGetWindowProperty ( qt_xdisplay(), qt_xrootwin( screen ), icc_atom, 0, INT_MAX, False, 
XA_CARDINAL, &type, &format, &nitems, &bytes_after, (unsigned char **)&str)) {
                if( nitems )
                        profile = cmsOpenProfileFromMem(str, nitems);
                XFree (str);
                return new KisProfile(profile);
        } else {
                kdDebug() << "No profile, not correcting" << endl;
