Could this library benefit from C#9's function pointers?

There might be function pointers to unmanaged APIs in C#:

Could this library benefit form that? Someone mentions here that this might be suitable for graphics APIs:

If so, I'd like to contribute.

Start by reading the linked C# 9 function-pointers proposal and the referenced discussion about graphics APIs, then inspect how this Direct2D library currently accesses unmanaged APIs. Done means establishing whether function pointers provide a meaningful benefit here and defining a concrete, testable scope for any resulting change.
