[ptx] Enblend-1.2

[Andrew C Mihal]

I put a new release up on the webpage.

http://www-cad.eecs.berkeley.edu/~mihal/enblend/

Version 1.1 did not completely fix an issue where perfectly horizontal or
vertical seams would appear sometimes in the output. If you have
encountered artifacts like that, give this version a try.
