[luatex] luamplib

[Keith J. Schultz]

Hi Herbert,

Using TexLive 2012 I get the result as in  http://perce.de/pub/mpost.png
in the produced pdf.

Using the latest LuaTeX 0.74 from TLContrib I get the result as in 
http://perce.de/pub/mplib.png !

So, there is probably a bug in the luamplib in LuaTeX 0.74!

What I have notice is that using LuaTeX 0.74 it takes almost I would say 
ten times as long to process the file!! 

regards
	Keith.
