API addition to SplitPane

Weighting systems are quite common but I agree with Jasper here.  As 
long as we haven't closed the door to one in future should we decide to 
go that way.

Where the main content area is resized on window resize and the side panels will remain the same size. All applications we found fall into this use case.
