Barack Obama Birth Certificate Image Tampering Analysis, Redux

The thread that would not die. Apparently "OpenDNA" has now made a template birth certificate you can download and make your own Hawaiian Certificate of Live Birth for fun and profit.

That, and most custom controls have annoying feature or performance deficiencies. So, I'm pretty good at hacking on the Win32 API.
