* Updates for many of the Diffusion_tensor system tests. This is due to the changed directory names in test_suite/shared_data/diffusion_tensor/. The ds.diff_dir variable has been introduced to point to the correct data directory.
* Large improvement for the GUI test tearDown() clean up method, fixing the tests on wxPython 2.8. The user function window destruction has been shifted into a new clean_up_windows() method which is executed via wx.CallAfter() to avoid racing conditions. In addition, the spin viewer window is destroyed between tests. The spin viewer window change allows the GUI tests to pass on wxPython 2.8 again. This also allows the GUI tests to progress much further on Mac OS X systems before they crash again for some other reason. This could simply be hiding a problem in the spin viewer window. However it is likely to be a racing problem only triggered by the super fast speed of the GUI tests and a normal user would never be able to operate the GUI on the millisecond timescale and hence may never see it.
* Reverted the wxPython 2.8 warning printout when starting relax, introduced in [[relax 3.3.5]].* Reverted the skipping of the GUI tests on wxPython 2.8, introduced in [[relax 3.3.5]].* Reverted the General.test_bug_23187_residue_delete_gui GUI test disabling, introduced in [[relax 3.3.5]]. The 'Bus Error' on Mac OS X due to this test is no longer an issue, as the spin viewer window is now destroyed after each GUI test.
* Created a special Destroy() method for the spin viewer window. This is for greater control of the spin viewer window destruction. First the methods registered with the observer objects are unregistered, then the children of the spin viewer window are destroyed, and finally the main spin viewer window is destroyed. This change saves a lot of GUI resources in the GUI tests (there is a large reduction in 'User Objects' and 'GDI Objects' used on MS Windows systems, hence an equivalent resource reduction on other operating systems).
* Fix for the GUI test clean_up_windows() method called from tearDown(). The user function window (Wiz_window) must be closed before the user function page (Uf_page), so that the Wiz_window._handler_close() can still operate the methods of the Uf_page. This avoids a huge quantity of these errors: Traceback (most recent call last): __getattr__ wx._core.PyDeadObjectError: The C++ part of the Uf_page object has been deleted, attribute access no longer allowed.
