+Description: workaround for headers missing from 'puredata'
+ Currently the 'puredata' package only includes the header m_pd.h, but other
+ headers are need to build this package, specifically s_stuff.h and
+ g_canvas.h.  This patch adds the two headers from 'puredata' version 0.42.6
+ until the other headers are included in Debian.

++/* 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", also called "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.
