BorderPane ignores managed property?

[Scott Palmer]

For the record I believe this is the issue I need to workaround in ScrollPane
http://javafx-jira.kenai.com/browse/RT-20698

That is the primary reason we have rolled our own ScrollPane equivalent.  We allow dragging of some nodes that are in the content of the ScrollPane and this can cause the content to change size.  When the ScrollPane is not positioned at 0 and the content shrinks - it flickers like mad.

(It also appears that our version has improved performance, but we are not extending Control and doing it "the right way".)

I am rolling my own scroll pane because there is a horrible flickering bug in the standard ScrollPane when the content size changes and the scroll position isn't at 0 (bug report on the way soon).
