// The GroupTabView is a UIView that displays combinations of snapshots,
// favicons and a label displaying the remaining unshowed tabs in a group. It is
// used in 3 different configurations, this view can be reconfigured without the
// need to be recreated.
// - Snapshot configuration: in this configuration, `GroupTabView` is similar to
// TopAlignedImageView. The associated favicon is placed on bottom right on top
// of the snapshot.
// - Favicons configuration: in this configuration, `GroupTabView` will display
// from 1 to 4 "favicon view" disposed on square shape. The "favicon view" is a
// UIImageView with the favicon as its image. The image will be centered. This
// configuration is called only when there is only favicons to display.
// - Favicons with tabs num configuration: When the number of tabs in a group
// exceeds 7, GroupTabView will display the same configuration as the favicons
// one, but the last element is a UILabel with different configurations (+N when
// N<100 and 99+ when N>99, where N represents the number of remaining tabs).
