MC-155104 fix

fixes MC-155104, an issue specific to 1.13-1.14.3 (early LWJGL 3 versions) where the mouse offset in GUIs will apply to the next mouse movement after exiting, snapping the player's view. Happens in Wayland but not XWayland and Windows for me, did not test macOS (there are many similar bugs in the history of Minecraft that this mod does not fix, including the one in GLFW on macOS that happens across more versions).

The Ornithe build is for generation 2 intermediaries, which are not ready for user adoption quite yet. However, they will become the default soon.
