tdf#147818 EMF+ Fix restoring clipping states
With previous implementation the clipping restoring with EmfPlusRecordTypeRestore was implemented wrongly as it is only taken to account the shape of clipping (state.getClipPolyPolygon) and doesn't take if clipping was even enabled (state.getClipPolyPolygonActive). Additionally the changing states should be made by using method: wmfemfhelper::HandleNewClipRegion() and not directly. The similar implementation was applied also to EmfPlusRecordTypeGetDC. Additionally the clipping for EmfPlusRecordTypeSetClipRect EmfPlusRecordTypeSetClipPath EmfPlusRecordTypeSetClipRegion was fixed, as initially the clipping is disabled (state.getClipPolyPolygonActive) and the clipping shape is empty (state.getClipPolyPolygon). It means that combination other than EmfPlusCombineModeReplace, was not working correctly. With this implementation, if Clipping is disabled, then treat clip combining in special way.
