Landscape layouts

[BenHenning]

Many users prefer to use landscape mode in apps, and Oppia's player view has good potential to better leverage landscape (e.g. having the content & interactions side-by-side rather than top-on-bottom). Although not a specific necessity for the prototype, supporting landscape layouts would go a long way toward demonstrating a well-rounded and polished user experience.

If this is not completed for the prototype, the app should instead be frozen in portrait mode until proper landscape support can be added.

Since this affects all screens in the app, it's potentially blocked by #51, #52, #53, #54, #55, #48, #46, #44, #42, #41, #40, #27, #28, #29, #30, #31, #32, #33, #34, #35, #26, #25, #24, #23, and #22. There may be future UI work that require landscape layouts work not linked here, and not all of the above layouts will require landscape-specific work. This can also be done during the development of those features, and in multiple pieces in order to optimize the landscape experience for users.

@rt4914 After the last gsoc, I think we had covered almost everything for landscape view.
Can we close this issue?

@anandwana001 Actually that project covered some of the major screen but not all. As per this document there are multiple screens which are pending.
