This helps to tell when a pointer is expected to be null, and avoid
overly verbose code when dereferencing. This commit also includes
a few other cleanups in this area:
- Use const in a few places
- Use `float2` instead of `float[2]`
- Remove some unnecessary includes and old code
The change can be continued further in the future.
The issue was that this menu was only looking at socket templates,
but not at the new node declarations. This fix is to just check those
as well. The fix comes with a small refactor that makes the memory
management a bit simpler.

related errors.
The goal is to be able to use C++ data structures to simplify the code.
