The underlying pressure was from xcalibrate never having been merged
into x11 and hence needing to replace xtscal by xinput-calibrate. With
that change, the need for tslib wasn't clear.

Its was also frustrating having two sets of pointercal files, one for
xinput-calibrate and one for tslib.

That said, I can see the need for tslib and if that is the only way to
support these touchscreens in qt5/qt4 we might have to reconsider that.

Are you sure the kernel interfaces that xinput is using don't work for
qt4/qt5? If not, we may need to reconsider tslib...
