path: root/debian/patches/add_required_internal_pd_headers

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 m_imp.h, g_all_guis.h, 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.
