Is there a reason FillMode.Point is not implemented?
Best wishes.
It was not in XNA and is not supported by Direct3D.
"not supported by Direct3D"
Hm, this is not correct at all, I guess: https://docs.microsoft.com/en-us/previous-versions/windows/desktop/bb322859(v%3Dvs.85)
Those are the D3D9 docs. MonoGame uses Direct3D 11 which no longer has the point fillmode: https://docs.microsoft.com/en-us/windows/win32/api/d3d11/ne-d3d11-d3d11_fill_mode
