-/* 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.
