"""
Make gistC module compatible with _tkinter module
(The work is done when this module is imported.)
Need to ensure two things:
(1) pyg_idler gets called by tcl/tk as an "after idle" method
- this allows gist to complete deferred actions
(2) pyg_pending gets called by tcl/tk whenever events arrive for
a gist window
- this is unnecessary under win32 because the OS automatically
sends window messages to the gist winproc

Initialization for Tkinter cooperating with Gist
