   I wonder if there's something else going on there.  I was writing  
GL code (not OpenGL) in 1991, running on a 12MHz (yes twelve) R2000  
CPU with a very simplistic hardware-assisted graphics subsystem, that  
threw lines up on the screen so fast it'd make your head spin.  Why  
would something like OpenGL primitive execution for simple line  
drawing be so slow in this day and age?
