No need for "public" here.

SameSize structures don’t really need to use smart pointers instead of raw pointers.

Should just call create here, not FillLayer::create.

I suggest not inlining these. We’d rather inline the constructor inside the create function rather than inlining the allocation and then paying function call overhead to call the constructor.

Should call just "create" and should write as a one-liner:

    Ref<FillLayer> copy() const { return create(*this); }

Thanks for the review!

Removed the public!

Changed back to a raw pointer.

Removed the FillLayer::

Sounds good — moved the definition out of the header.

Done!
