Prevent accuracy degradation of signed distance computation

2

Signed distance computation using fast winding number (i.e. `(1.0 - 2.0 * winding_num) * udist`) degrades accuracy, since fast winding number contains approximation errors. This PR replaces `(1.0 - 2.0...

Fix transform_view::iterator::iterator_category when iter_reference_t is not an lvalue ref

4

Since `iter_reference_t` can be a type that is not an lvalue-reference, the current wording on its `iterator_category` needs to be fixed. ## Proposed Resolution Change [range.transform.iterator] p2 as follows: ```diff...

Precondition for `advance(i, n)`

2

In [iterator.operations] `advance` does not have a requirement on iterator validity, but I think something like this is needed: - For non-negative `n`, [it, itn) should be a valid range,...
