+ * 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,
