-Add a hack to GreStretchBltMask to return TRUE when a dimension is 0. After some
investigation it seems that windows returns TRUE in such a case but couldn't
investigate more if this change is really correct. This hack is needed because a drawing
operation in uxtheme is aborted when StretchBlt returns FALSE
