Description: 
When user is in landscape orientation then enters into task manager, and opens a non-landscape application, the transition is slow and unsightly.

Repro Steps:

2) Open Contacts then open Gallery app.
3) Activate landscape orientation in Gallery app. 
4) Activate card view and open a non-landscape application.

Actual Results: 
Opening a portrait-only app while in landscape card view mode causes a poor window transition. 

Expected:
Opening a portrait-only app while in landscape card view shows a smooth window transition.

[Derek Harris [:DerekH] - Dont need info. Last day 6/5/15]

This is a slow transition and is poor UX due to this happening every time a user enters a portrait locked app. This is a new feature for 2.2 so NI Window Management owner for 2.2 Blocking decision.

NI Hermes for this.

I've added this to meta bug 1111795 as one of a list of orientation-related task manager bugs we want to get into 2.2

[Sam Foster [:sfoster] (he/him)]

We're locking task-manager/card view orientation in bug 1118390, which removes the possibility of landscape to portrait transition.
