v1.1.2: Mixed Reality, Leap Motion, Grip-to-Grab — EXA: The Infinite Instrument Steam update #1414978

EXA gets experimental in this version, with new mixed reality modes and Leap Motion hand input. With mixed reality, you'll find an improvement to the standard SteamVR approach, and also a custom, in-app method of creating mixed reality. The use of Leap Motion hands input is provided as a proof-of-concept, without significant refinement, so using the Vive/Oculus controllers is still highly recommended. Other improvements in this version include a "grip-to-grab" feature (which provides an alternative to the "grab" tool), improved loop grid visuals, and a variety of other minor changes and fixes.
