[ptx] Enblend 2.0!

[Andrew C Mihal]

Today I'm releasing Enblend 2.0.

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

New features include:

 * Support for signed and unsigned 16-bit, 32-bit, single- and 
double-precision floating point pixel types.

 * No more banding artifacts in the sky, even with 8-bit images.

 * Sophisticated memory/disk balancing. You can tell Enblend how much 
memory it is allowed to use, and it will swap to disk after that.

 * Support for large panoramas. I have tested that Enblend can blend a 1.2 
gigapixel, 16-bit per channel color image. You should be able to go right 
up to 4 gigabyte limit of the TIFF format.

 * Optional blending in CIE L*a*b* color space.

There are also some new articles on the web page, including a discussion
on the banding artifacts in the sky, and some details on how Enblend
works.
