- Adjust sizes before applying them into items to keep the items inside minimum and maximum sizes. Also avoids calling items setWidth/setHeight multiple times during layout. - Enforce items staying inside SplitView size instead of having preferred size initially and enfocing only after handle resizes. - Don't resize handles in componentComplete as sizes are not correct yet and initial resizing is done in createHandleItem. - Adjust autotests to pass now that size limits are enforced. Width getting value of preferredWidth requires polish.
