- *
- * "(11) Typically, OpenGL specifies that if an error is generated by a
- * command, that command has no effect. This is somewhat
- * unfortunate for multi-bind commands, because it would require a
- * first pass to scan the entire list of bound objects for errors
- * and then a second pass to actually perform the bindings.
- * Should we have different error semantics?
- *
- * RESOLVED: Yes. In this specification, when the parameters for
- * one of the <count> binding points are invalid, that binding point
- * is not updated and an error will be generated. However, other
- * binding points in the same command will be updated if their
- * parameters are valid and no other error occurs."
