/* Which monitor is this window on, and what ICC profile has the OS attached to it?
 *
 * This is hardware interrogation -- the same category as querying RAM or CPU features --
 * and it lived in common/colorspaces.c only because that is who consumes the answer.
 *
 * It is unavoidably windowing-system code: the monitor is identified BY the window shown
 * on it, and each platform answers differently (X11 _ICC_PROFILE atom, the Windows colour
 * API, the macOS ColorSync API). It therefore depends on GDK/GTK -- an external library,
 * not on src/gui/ -- so nothing here inverts the layer order.
 *
 * The caller supplies the widget. This module never asks the GUI which window to look at;
 * that decision belongs to whoever owns the window.
