This was added a long time ago in 42bbd5c9ae06a8d8ffb7915599097ead6f848755
and meant to fix prevent the view becoming black when jumping into a
ceiling, this no longer happens today.
Removes duplicated offset calculations from Game and use whatever the Camera class returns.
This keeps the eye position nicely in sync, and gets rid of duplicated code.
GenericCAO::getPosition() did not take the camera offset into account
LocalPlayer attachment cleanup: Use sane getParent() function
Make that getPosition() (GenericCAO and LocalPlayer) always return the absolute position
In pitch fly mode, you fly to the exact direction you are pointing at, using the forward key. Other move directions are also pitched accordingly.
It allows smoother and more complex movements.
Can be enabled/disabled by L key by default (set keymap_pitchfly in minetest.conf)
