First, if the global properties that Phil lists are empty, what's the  
best way to determine that my code is running in a Revlet?

Second, some of my apps have a zillion referenced images that build  
the UI. Will I have to define new paths for them on preopenstack or  
preopencard? No shortcut way? I wonder whether I'll have to come up  
with a scheme to cache images...
