The GLenum typealias is: typealias GLenum = UInt32

However, the enum values themselves are defined as Int32 values:

…
var GL_TEXTURE_BINDING_2D: Int32 { get }
var GL_TEXTURE_WIDTH: Int32 { get }
var GL_TEXTURE_HEIGHT: Int32 { get }
….

So when passing them into functions, like:

        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);

Does not work. Instead, we have to cast the values:

        glTexParameteri(UInt32(GL_TEXTURE_2D), UInt32(GL_TEXTURE_MIN_FILTER), GL_LINEAR);

That’s broken. Please fix.
