[issue19085] Add tkinter basic options tests

[Serhiy Storchaka]

Thanks Vajrasky. Now I see that this is a bug in Tk 8.5 which was fixed in 8.5.12. We should use round() to conform with last Tk patchlevels. However this breaks tests on Ubuntu 12.04 LTS which uses 8.5.11.

Here is a patch which adds workaround for this bug.
