The conversion is as follows: - GraphicsFilter::FILTER_NEAREST == gfx::Filter::POINT - GraphicsFilter::FILTER_GOOD == gfx::Filter::GOOD - GraphicsFilter::FILTER_BEST == gfx::Filter::LINEAR Also typedef GraphicsFilter to gfx::Filter; this will be removed in the next patch. These changes mean ToFilter() and ThebesFilter() are no longer needed.
