Here is a patch which adds tests for Tk geometry managers (pack, place and grid). In additional it fixes the grid_columnconfigure() and grid_rowconfigure() methods which did not worked with wantobject=True (preferable and default mode).

On OS X 10.9 with Cocoa Tk 8.15.0+, Cocoa Tk 8.6, and X11 Tk 8.6:

With OS X Carbon Tk 8.4, the grid_anchor and grid_configure tests fail:

My fault. I tested the patch with 8.5 and 8.6, but was too lazy to check it with 8.4. Here is updated patch with workarounded 8.4 peculiarities.

I'm not sure about test_place_forget(). I have removed the check, hope this will help.

Thank you Ned.

With test_geometry_managers_2.patch, test_tk now passes with all of the previously tested OS X Tk versions.

Unfortunately new tests emit on 3.3 and 2.7 same warnings as in issue20567. So I have committed only the fix, without tests.
