Using the DPI from Application::GetDefaultDevice() is a much better idea, especially that now oox::GraphicHelper::GraphicHelper() and oox::drawingml::DrawingML::WriteSrcRect() are in sync. Should fix the testCropPixel() failure in CppunitTest_sw_ooxmlexport that appears on HiDPI systems. Also, fix all the rounding problems that now became visible when the DPI is the same for both import and export.
