[metapost] Better gradient and 'special'

[Jesús Guillermo Andrade]

It seems very interesting what Mr. Siebenmann is suggesting: AFAIK  
there is no mention about the "special" command changes. Perhaps in  
the next version the will add it?. I wish I was an expert. The sad  
thing regarding the issue is that when I compare the same logo I did  
with a linear gradient against the same one produced by Adobe  
Illustrator, the metapost version is 4 times bigger.
Kind of strange right?
