Hi, I was running
gl.glVertexAttribPointer(attributeLocation, 2, GL.GL_UNSIGNED_INT, false, stride, 0)
and it refused to work until I switched to GL.GL_FLOAT which seems very weird, and if anybody has an explanation for that then I'd be glad to hear it, but my main question is something else:  In the process of fiddling with this I learned about glVertexAttribIPointer() which seemed like something I ought to try, since I was passing ints and that function seems to be specialized for ints or something.  But the interfaces GL4 and GL3 seem to lack glVertexAttribIPointer(int, int, int, int, long).  I'm using a GL3, which should have that method.  What's the problem?
