can't trigger unity launcher when using wacom tablet in absolute mode

[Jack Leigh]

Set unity launcher to autohide
Use wacom tablet in absolute mode (pen rather than mouse)
Try to reveal launcher

Launcher doesn't reveal.

I guess it makes sense since there is no pressure on the edge but it is not ideal.
