8u40 API proposal: ScrollPane's minViewportWidth/minViewportHeight

[Martin Sladecek]

Hello,
I propose to add 2 additional properties to ScrollPane: 
minViewportHeight and minViewportWidth.
They should work the same way as prefViewportWidth/prefViewportHeight, 
specifying the minimum size for the viewport, not ScrollPane as a whole.

JIRA: https://javafx-jira.kenai.com/browse/RT-37407
webrev: http://cr.openjdk.java.net/~msladecek/rt-37407/webrev.00/

Thanks,
-Martin
