  * @brief The GridResizeSlider class
  * The GridResizeSlider is a QSlider that ties into the ThumbnailView infrastructure,
  * as well as into the SettingsData on thumbnail size.
  *
  * Moving the slider changes the displayed thumbnail size, and changing the
  * thumbnail size in the SettingsData reflects on the slider.
  * Changes in SettingsData::thumbnailSize() are reflected in the maximum slider value.
