@interface MDCBottomDrawerTransitionController : NSObject <UIViewControllerAnimatedTransitioning, UIViewControllerTransitioningDelegate>
The transitioning delegate to use for presenting a view controller as a MDC bottom drawer.
Setting the tracking scroll view allows the drawer scroll the content seamlessly as part of the drawer movement. This allows the provided scroll view to load the visible content as the drawer moves, and therefore not load all the content at once and allow to reuse the cells when using a UICollectionView or UITableView.
