    paths: *mut sg_path_arena,

Adds new scope stacks to the path arena. count is the number of scope stacks you want to create. The content of each scope stack comes from two arrays. The lengths array must have count elements, and provides the number of scopes in each scope stack. The scopes array contains the contents of each of these scope stacks in one contiguous array. Its length must be the sum of all of the counts in the lengths array.

You must also provide an out array, which must also have room for count elements. We will fill this array in with the sg_scope_stack instances for each scope stack that is created.
