    Add bug10297.patch. (Set CREATE_NO_WINDOW.)
    
    This is the patch from #10297, that causes Tor to set the
    CREATE_NO_WINDOW flag so console windows don't appear. It has been
    applied to tor master but not yet to TOR_TAG.

+Subject: [PATCH] Set CREATE_NO_WINDOW in tor_spawn_background.
+
+This flag prevents the creation of a console window popup on Windows. We
+need it for pluggable transport executables--otherwise you get blank
+console windows when you launch the 3.x browser bundle with transports
+enabled.
+
+http://msdn.microsoft.com/en-us/library/ms684863.aspx#CREATE_NO_WINDOW
+
+The browser bundles that used Vidalia used to set this flag when
+launching tor itself; it was apparently inherited by the pluggable
+transports launched by tor. In the 3.x bundles, tor is launched by some
+JavaScript code, which doesn't have the ability to set CREATE_NO_WINDOW.
+tor itself is now being compiled with the -mwindows option, so that it
+is a GUI application, not a console application, and doesn't show a
+console window in any case. This workaround doesn't work for pluggable
+transports, because they need to be able to write control messages to
+stdout.
