Pointers and Generics Are Not Handled with Projected Types

[JasonBock]

To reproduce:

public interface ISurface
{
  unsafe void Create<T>(T* allocator) where T : unmanaged;
}

var expectations = Rock.Create<ISurface>();

This causes errors like:

Error - Id: CS0208, Description: Rocks\Rocks.RockCreateGenerator\IVkSurface_Rock_Create.g.cs(13,63): error CS0208: Cannot take the address of, get the size of, or declare a pointer to a managed type ('T')
Error - Id: CS0246, Description: Rocks\Rocks.RockCreateGenerator\IVkSurface_Rock_Create.g.cs(13,63): error CS0246: The type or namespace name 'T' could not be found (are you missing a using directive or an assembly reference?)
Error - Id: CS1503, Description: Rocks\Rocks.RockCreateGenerator\IVkSurface_Rock_Create.g.cs(173,175): error CS1503: Argument 1: cannot convert from 'T* [Rocks\Rocks.RockCreateGenerator\IVkSurface_Rock_Create.g.cs(165)]' to 'T* [generator, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]'

The problem is the projected ArgumentEvaluationForTPointer delegate doesn't expose the T generic parameter, nor does it show up for ArgumentForTPointer. If that would trickle through (with the appropriate where T : unmanaged), then this should work.

Another possibility is to create UnmanagedArgument<T> where T : unmanaged, and see if that can be used when a pointer is in play with a generic (or even if it just shows up like int*, maybe....this will take some investigation).

This showed up wtih Silk.NET.Core.Contexts.IVkSurface
