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!)
