[New] The divider drawing handler includes the splitview as a param
[New] Delegate can hide dividers when adjacent subviews are collapsed
[Fix] -setSplitView avoids removing all info if the splitview didn't change
[Fix] Fixes subtle bugs in the divider constraint dragging.
Caused by a misleading parameter name.
Avoids enumerating on mSubviewInfos and instead directly goes by subview index
Avoids an infinite loop in _resizePriority where the delta may not
change when resizing subviews under really really strange circumstances.
I'm not sure what caused it. One of these days a better algorithm
would be useful.
