/* 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.
