I think the usual UIKit style for private properties is to omit the underscore from the property name and define both setter=_setProperty: and getter=_property.

If we don't define this method, the compiler should autosynthesize it and the ivar for us.

We've decided against doing that for properties. If we decide to make a private property public with slightly different semantics we don't want clients to break.

Not sure why committing is separate from setting.

_setObscuredInsets

Need a better name for this, or use a flag on -_setObscuredInsets:

Ben and I discussed this, and we think it makes sense to have a pair of methods:
- (void)beginInteractiveObscuredInsetChange;
- (void)endInteractiveObscuredInsetChange;
When every begin call has been balanced by an end call, we'll inform the web content of the change.
