Subject: [PATCH] ft-pointer: without gaze mode, a pinch is a real press

Pressed when the pinch closes, released when it opens, its hand dragging
the pointer in between (at the pinch gain, past the dead zone), like the
mouse's button. That's what the gaze probe's Click practice needs: it
freezes its own gaze dot at the press and drags it by the pointer's
movement until the release. With gaze mode on, the pinch still holds the
press back and clicks on the release.
