Release 57.1:
Bugfix: have websurfaces only make request with server once (instead of repeatedly polling until loaded)
Bugfix for Oculus Touch users and walking "sticking" after text
Bugfix: no more tooltips hanging around after clicking e.g. the pocketspace button in 2DUI with mouse
Improvements to virtual keyboard so it can be used two-handed
Minor bugfix to set tex_linear, etc for non-OBJ types
Bugfix: fixed avatar animation "jitter" bug, alternating between idle and jump animations
Middle click for drag+drop, drag and dropping of PDF files
Linux build now attempts to initialize/use OpenVR (until Vulkan support is ready - your mileage may vary!)
