// This class creates an image view, a label and 2 buttons. This view can be
// configured with 2 modes : "Cold State" and "Warm State".
// + "Cold State" mode displays the chomium icon in the image view, and only
//   displays the primary button.
// + "Warm State" mode displays the image view (big than the cold state mode),
//   displays both buttons.
//
//  For the warm state, the owner should set:
//   - the image for `imageView`, using -[SigninPromoView setProfileImage:]
//   - the label for `textLabel`
//   - the title for `primaryButton`
//   - the title for `secondaryButton`
