wxPython 2.1b1:

wxPython 2.1b1:

	Added the missing wxWindow.GetUpdateRegion() method.

	Made a new change in SWIG (update your patches everybody) that
	provides a fix for global shadow objects that get an exception in
	their __del__ when their extension module has already been deleted.
	It was only a 1 line change in .../SWIG/Modules/pycpp.cxx at about
	line 496 if you want to do it by hand.

	It is now possible to run through MainLoop more than once in any one
	process.  The cleanup that used to happen as MainLoop completed (and
	prevented it from running again) has been delayed until the wxc module
	is being unloaded by Python.

	wxWindow.PopupMenu() now takes a wxPoint instead of  x,y.  Added
	wxWindow.PopupMenuXY to be consistent with some other methods.

	Added wxGrid.SetEditInPlace and wxGrid.GetEditInPlace.

	You can now provide your own app.MainLoop method.  See
	wxPython/demo/demoMainLoop.py for an example and some explaination.

	Got the in-place-edit for the wxTreeCtrl fixed and added some demo
	code to show how to use it.

	Put the wxIcon constructor back in for GTK as it now has one that
	matches MSW's.

	Added wxGrid.GetCells

	Added wxSystemSettings static methods as functions with names like
	wxSystemSettings_GetSystemColour.

	Removed wxPyMenu since using menu callbacks have been depreciated in
	wxWindows.  Use wxMenu and events instead.

	Added alternate wxBitmap constructor (for MSW only) as
	      wxBitmapFromData(data, type, width, height, depth = 1)

	Added a helper function named wxPyTypeCast that can convert shadow
	objects of one type into shadow objects of another type.  (Like doing
	a down-cast.)  See the implementation in wx.py for some docs.
