How to implement drawScreenshotOnFolds? 

Hi,

I need to be able to trigger a repaint of a folded up view. If I change the content of the container left/right views, the folded screenshot images don't update until the view is folded all the way out. So, I need to be able to call the PaperFold drawScreenshotOnFolds method on the left/right views. 

Can this be done?
