+ Added the ability for vehicles to collide with and rest on planetary surfaces. This is a very simple version to start which treats the vehicle as an analytic sphere and only collides directly in the radial direction. It also does not take the surface normal into account at the moment.
+ Added a symplectic Euler integrator which we use to resolve collision along with a scheme of sequential impulses.
* Major rework to vehicle state and update logic. We can now choose multiple different update methods within a single frame - for example, taking a Kepler step to the edge of the atmosphere, integrating with velocity Verlet to the surface, and resolving and impact with symplectic Euler.
* Added a minimum target framerate to prevent the FPS "death spiral" when there is too much work to get done in a single frame, so the target frame time increases exponentially each time. We will now scale back the time compression rate to try and fit within a reasonable frame rate.
+ Added a new Simulation tab to the game settings for various physics parameters.
* Adjusted celestial creation to be a full preorder traversal, meaning each celestial is fully baked before its children are instantiated.
* Lowered the minimum camera altitude to 0.5 meters.
+ Added some float3 extension methods and renamed DoubleVectorEx to Double3Ex.
+ Added a physics debug window.
* Changed the patched conics parent impact detector to use a direct calculation rather than a bisect search.
* Fixed attitude snapping using the wrong coordinate frame rates.
+ Fixed debug thruster arrows being drawn in the wrong location.
+ Added LC-39A to Earth landmarks.
