Comment 30 for bug 742567

Unlike swap axes, the coordinate transformation does not work properly at least not with all devices. First, the wiki is in error, the correct transformation for a rotate left is 0 -1 1 1 0 0 0 0 1 and not 0 -1 0 1 0 0 0 0 1. However with Ubuntu 11.04 and a Lenovo S-10t3 when the axes are reversed with this transformation touching the screen results in the correct location of the pointer, but dragging on the screen causes the pointer to jump wildly from the correct location to an alternative location. It's hard to see in what sense the problem has been fixed by dropping a procedure (swap axes) that worked and replacing it with one (coordinate transformations) that doesn't work.
