- * happen to use VBOs, without also supporting the full tracking of VBO vs
- * user vertex array bindings per attribute on each vertex array for
- * determining what to upload at draw call time.
- *
- * Note that GL core makes it so that a buffer binding with an invalid handle
- * in the "buffer" parameter will throw an error, and then a
- * glVertexAttribPointer() that followsmight not end up pointing at a VBO.
- * However, in GL core the draw call would throw an error as well, so we don't
- * really care if our tracking is wrong for this case -- we never need to
- * marshal user data for draw calls, and the unmarshal will just generate an
- * error or not as appropriate.
- *
- * For compatibility GL, we do need to accurately know whether the draw call
- * on the unmarshal side will dereference a user pointer or load data from a
- * VBO per vertex. That would make it seem like we need to track whether a
- * "buffer" is valid, so that we can know when an error will be generated
- * instead of updating the binding. However, compat GL has the ridiculous
- * feature that if you pass a bad name, it just gens a buffer object for you,
- * so we escape without having to know if things are valid or not.
