I have a need to apply the CSS so when I 'snapshot' a node that isn't in my
scene, it looks correct.
I'm doing this:
Parent p = n.getParent(); // The node I want tosnapshot isn't the root of
the graph
Scene s = KayakFXUtils.createDarkScene(p,1000,1000);
n.impl_processCSS(true);
n.layout();

I get a reasonable size for the node, but the CSS isn't applied.

I get a ton of warnings like this:

WARNING: com.sun.javafx.css.StyleHelper calculateValue Could not resolve
'-fx-text-background-color' while resolving lookups for '-fx-text-fill'
from rule '*.label' in stylesheet
jar:file:/C:/Program%20Files%20(x86)/Java/jdk1.7.0_40/jre/lib/jfxrt.jar!/com/sun/javafx/scene/control/skin/caspian/caspian.bss

Ideas?
