what is "pin"? bg is a feature not officially in SafeFrames 1.x (although Yahoo does have this functionality)

I am using the code linked from http://safeframes.net/ which points to sourceforge. The runtime objects have these properties. The code in this repo has the same properties.

the properties being there doesn't mean anything for "bg" and "pin". Both are non-standard things, left overs from the port. "par" on the geometry object actually is documented somewhere b/c I know we'd missed it before. . .

"par" is basically the parent owner dimensions/rectangle, which may be the page body, or may be a scrollable div/container of some sort depending on the publisher side dom.

"bg" is a rich-media feature that likely will be there in the next revision (if we can ever get too it, and as I said it already exists at Yahoo!'s version). "pin" is not. . .
