Description

Hi,

the function which checks the proximity to celestial bodies in the next gametick seems to use a projection of the arc length to check in advance wether entrance into atmosphere or a lower "warp-maximum-zone" is to be expected.
The function projects the trajectory only clockwise into the future, reducing or stopping the warp if a lower celestial orbit distance magnitude is to be expected.

How the glitch works:
Orbiting a planet counter-clockwise will render the function out of context:
The warp will be stopped after the atmosphere has already been passed.
Intitiation of warp shortly after passing the athmospere will not function.
Initiating a high warp after having left the atmosphere for a while will work, but get stopped immediately, because the function expects the trajectory to lead into the atmosphere and stop it immediately.

Testconditions for confirmation:
Launch a vessel counter-clockwise into a suborbital trajectory (for example: periapsis 60km, apoapsis 500,000km).
Initiating highspeed-warp after leaving atmosphere will not work or get aborted.
Initiating highspeed-warp before entering atmosphere will bypass the atmosphere and stop in the middle of atmosphere or after leaving atmosphere.

Solution:
Make the function which projects future trajectory case sensitive to signum of projected arc length direction.

Status: New (no prior reports found)
Priority: Normal (high and gamebreaking since vehicles may get destroyed by planetary colission when warp doesnt stop in time, but high workload for correcting the glitch gives it a bad "benefit/workload"-ratio)
Category: Physics (programmingwise it falls into the collisiondetection and math categories)
Version: 1.1.2 (Realized the bug here for first time)
Platform: Windows (tested on Windows10, but probably present on all Platforms, since its a platform-independant calculation)
