Hello,

I propose to add new callback in Splitter class: WhenEndResize.

This callback is very important when i have a ImageCtrl or other control that takes time on refreshing data by resizing (raster size by ctrl size to a big image).

The patch is:

Well, I have simplified and renamed to WhenSplitFinish (to get the name inline with SliderCtrl) - other than that, it is done.
