We have read that, but we had hard time to figure out the phrase "The origin is the center point of the three other transformations" because we are not native english speaker.
If i guess correctly the origin is the "started" point for all the 3: position, rotation and scale? if so, when we change the origin of a 32x32 sprite to (3,3) and we position it (50,50) the actual image start from (47,47)?
I'm sorry for my awful english writing.
