Fix drawing background in wxDataViewCtrl with rules

Browse Source 
wxRect to draw the background was prepared in a wrong way if wxDataView had
vertical or horizontal rules.

Fix this by adjusting the correct component of the rectangle when using
horizontal rules and by fixing an off by one bug when using vertical ones.
