Review Request: RT-36851 - preloaders don't work in packaged applicaitons

[Danno Ferrin]

Kevin, Stephen,
  Please review RT-36851.  There is one file in graphics in the application model affected by this change, and it is the most important change.  My rational is in the JIRA.

JIRA: https://javafx-jira.kenai.com/browse/RT-36851
WebRev: http://cr.openjdk.java.net/~shemnon/RT-36851/webrev.00/

Thanks,
