The last state of the experiment, kept on this branch only: - input/gazefirst.py, input/steamui.py: the relay reading the controllers from vrserver's web socket, switching the compositor binding, and driving the Steam UI filter (whose block now expires unless renewed). - The helper's trigger and bumper holds (steered by the controller's position), the laser keeper, and the click gate that waits for the laser. - pointer/probe/focustest (overlay flag 1 << 4, as an input client too), vrsetting (SteamVR settings through vrserver), lasertest --reclaim. Every press and release Steam sees takes SteamVR out of laser mode, and taking the laser back breaks clicks and drags. See docs/gaze-controllers.md on experimental.
