-/* this file defines the structure for "glists" and related structures and
-functions. "Glists" and "canvases" and "graphs" used to be different
-structures until being unified in version 0.35.
-
-A glist occupies its own window if the "gl_havewindow" flag is set. Its
-appearance on its "parent" or "owner" (if it has one) is as a graph if
-"gl_isgraph" is set, and otherwise as a text box.
-
-A glist is "root" if it has no owner, i.e., a document window. In this
-case "gl_havewindow" is always set.
-
-We maintain a list of root windows, so that we can traverse the whole
-collection of everything in a Pd process.
-
-If a glist has a window it may still not be "mapped." Miniaturized
-windows aren't mapped, for example, but a window is also not mapped
-immediately upon creation. In either case gl_havewindow is true but
-gl_mapped is false.
-
-Closing a non-root window makes it invisible; closing a root destroys it.
-
-A glist that's just a text object on its parent is always "toplevel." An
-embedded glist can switch back and forth to appear as a toplevel by double-
-clicking on it. Single-clicking a text box makes the toplevel become visible
-and raises the window it's in.
-
-If a glist shows up as a graph on its parent, the graph is blanked while the
-glist has its own window, even if miniaturized.
