[gtk/matthiasc/color-profiles: 8/12] Add gdk_surface_set_hdr

[Matthias Clasen <matthiasc src gnome org>]

commit 71f7a83afc381bf16f41ac5836697a7fd50b17ac
Author: Matthias Clasen <mclasen redhat com>

    Add gdk_surface_set_hdr
    
    Add private api to tell a GdkSurface that it should
    provide an HDR framebuffer (what that means is not
    precisely specified).
    
    Currently, this does nothing, since no backends
    implement the new vfunc.
