Provide common implementations for two operations that all Python FileHandlers will typically use. - `poll_file_object_drop` To be used inside the FileHandler `poll_drop` callback - `invoke_popup` To be used inside the Operator `invoke` callback The above code closely mirrors what is currently done inside the existing Blender c++ FileHandlers.
