I was referring to matrix as in linear algebra like you mentioned.
I no nothing about features that Jitter has.
This was one of the topics in math which I missed out in high school.
(Hey, wasn't goofing off.. schedules were conflicting with biology
Now that I've got a grasp of what they are good for in real (or virtual)
life, I enjoyed spending the last week or so studying math putting
patching aside. :(

Great, I wasn't quite sure on that.
Thanks again Mathieu, I think you've gifted me enough bases to start
building thoughts on this.
