I'm a very, very bad person.
I just couldn't bring myself to go back to work, so after some procrastination of a more mundane variety, I ported the C++ version of Habanero over to C#. It isn't very clean code yet - most of it is just one experimental hack after another - but I've successfully gotten a textured quad rendering again. Yayy!
That took about 2 hours, down sharply (urgh, no pun intended) from the C++ attempt. This language rocks.
So there you have it. Now I really need to get some real work done [grin]
