IGlHandleStruct

Description

Add interface for all GlHandles
Makes it possible to take a generic GlHandle for methods like GL.ObjectLabel.

Without generic implementations of those functions GL.ObjectLabel(identifier, IGLHandle name, int length, string label) would cause boxing, so the function should be

public void ObjectLabel<THandle>(identifier, THandle name, int length, string label) where THandle : IGLHandle

This would also have to work with the fact that by default typed handles are turned off.

Not sure what you mean about this.

But i didn't necessarily mean we should provide the overload for ObjectLabel. But in user code it would be possible to do stuff of that nature or similar. For example in my project using OpenTK 5, i have a base class for all GLObjects. public abstract class GLObjectBase<T> : IDisposeable But i would like to add a constraint to the template type. So it could only be a GL Handle.

Ah I see! Yeah we can add a common interface to the different handles sure.

In the next prerelease typed handles is going to be turned off. See #1545

One issue is that as it stands the typed handles are enums. Enums cannot implement interfaces. A struct can however.

They are not enums atm? They are structs.

I stand corrected, had to go back and verify.
