  * This file defines a special dispatch table which is loaded with no-op
  * functions.
  *
- * When there's no current rendering context, calling a GL function like
- * glBegin() is a no-op.  Apps should never normally do this.  So as a
- * debugging aid, each of the no-op functions will emit a warning to
- * stderr if the MESA_DEBUG or LIBGL_DEBUG env var is set.
+ * Mesa can register a "no-op handler function" which will be called in
+ * the event that a no-op function is called.
+ *
+ * In the past, the dispatch table was loaded with pointers to a single
+ * no-op function.  But that broke on Windows because the GL entrypoints
+ * use __stdcall convention.  __stdcall means the callee cleans up the
+ * stack.  So one no-op function can't properly clean up the stack.  This
+ * would lead to crashes.
+ *
+ * Another benefit of unique no-op functions is we can accurately report
+ * the function's name in an error message.
