We should have a consistent naming strategy for system properties.
Only properties that we plan to support in the long term should be prefixed with "javafx."

A search on the code based turned up the following properties:

binary.css
com.sun.browser.plugin
com.sun.javafx.fxvkContainerType
com.sun.javafx.multiTouch
com.sun.javafx.pointer
com.sun.javafx.touch
com.sun.javafx.twoLevelFocus
