This turns links red if no implicit conversion can be made between the
from socket and the to socket. For geometry nodes this happens with object,
geometry, collection, and string sockets that are connected to a different
type.
Valid connections:
| From socket | To socket |
| float, int, bool, vector, or rgba | float, int, bool, vector, or rgba |
| geometry | geometry |
| object | object |
| string | string |
| collection | collection |
