I think we're in agreement about what we can handle. We should be able
to handle whatever the kernel sends us. But I feel that it's impossible
to have a kernel device that sends touch information through the same
properties for different surfaces. Thus, we don't need per-axis touch modes.
To push towards a resolution to this issue, Peter, Ping, do you still
feel we will need per-axis touch modes? If you do, then I could use more
detail on how such a device would be defined through the evdev or touch
class interface. Maybe I'm missing something obvious?
