The problem is that for a given function, the docs for that function 
don't tell you which errors you could possibly see.  So there's the huge 
list of errors (said URL) and...which of those will I need to manage?  I 
can't know, either now, or with regard to future changes in behaviour. 
That means GLE is only guaranteed useful for handling specifically 
documented GLE error codes and for differentiating between no error and 
*an* error.
