[gtk/matthiasc/color-profiles: 13/32] gsk: Add hdr rendernode api

    gsk: Add hdr rendernode api
    
    Add private api to find out if the content
    of a render node should be considered HDR.
    
    Currently, this comes down to whether there are
    any texture nodes with HDR textures in the subtree.
