wx: Fix occasional seq fault after appliction stops

There seems to be a timeing dependent double delete when doing
reference cleanup after wx:destroy(). wxGraphicsObjects can thus not
be free'ed by wx in the cleanup phase. A guess is that the underlying
rendering context deletes all graphics objects without careeing about
wxWidgets reference counting.
