code: public static void setDpi(Resolution baseline, Config config)
      {
          Check.notNull(baseline);
          Check.notNull(config);
  
          setDpi(DpiType.from(baseline, config.getOutput()));
      }
docs: Set the DPI to use. Computed automatically depending of the baseline resolution and the current configuration.
  <p>
  Resources has to be suffixed with "_DPI" before the extension.
  For example, baseline resources is "image.png", support for other DPI will need:
  </p>
  <ul>
  <li>image_ldpi.png - support for low resolution</li>
  <li>image_mdpi.png - support for baseline resolution, same as image.png, not required</li>
  <li>image_hdpi.png - support for high resolution</li>
  <li>image_xhdpi.png - support for very high resolution</li>
  </ul>
  <p>
  If there is not dedicated DPI resource, the baseline one will be use instead.
  </p>
  <p>
  <b>Must be set after engine started, before resource loading.</b>
  </p>
  
  @param baseline The baseline resolution (must not be <code>null</code>).
  @param config The configuration used (must not be <code>null</code>).
  @throws LionEngineException If invalid arguments.
