During these days I have working with libccc, and after implemented a patch to create a more faster render I found a bug in get_all_bounds function, after append a cc_item in another cc_item the child item return empty values on get_all_bounds. Searching on the code I found the problem in function "cc_item_insert" because this register the same item twice and this case a problem in get_all_bounds.
I create this simple patch to fix this, I don't know if this is the best way to fix the problem, but with this patch all works fine.
