@interface NSView (RBLAnimationAdditions)
// Invokes +rbl_animate:completion: with a nil completion block.
+ (void)rbl_animate:(void (^)(void))animations;
// Executes the given animation block within a new NSAnimationContext. When all
// animations in the group complete or are canceled, the given completion block
// (if not nil) will be invoked.
+ (void)rbl_animate:(void (^)(void))animations completion:(void (^)(void))completion;
// Invokes +rbl_animate:completion:, setting the animation duration of the
// context before queuing the given animations.
+ (void)rbl_animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations completion:(void (^)(void))completion;
// Returns whether the calling code is executing in an animation context created
// by this category (like through -rbl_animate:completion:).
//
// This only describes whether an animation context is open, not if animations
// happen to be executing at the moment.
+ (BOOL)rbl_isInAnimationContext;
// Returns an animator proxy for the receiver if +rbl_isInAnimationContext
// returns YES. Otherwise, the receiver is returned (so that animating is
// effectively disabled).
