GravityShaderMirrorTests compares the expression of GravityField.Potential with gravityPotential in Gravity.cginc.
GravityFieldParityVerify now builds four off-axis bodies (one of mass 0), lowers through three frames with bodies moved
between them, and checks the map screen's gravity camera mask. RTS/Planet.prefab loses the Gravity Well object bound to
the Gravity Field material. Builds: yes (verify passes on Starfire; the new test is unrun until the Yggdrasil job).

Zone.WellReference owns each body's reference zero (GetHeight uses it). Gravity.cginc mirrors GravityField.Potential;
Brushes/Gravity Field draws depth = -h on layer 9 from a StructuredBuffer that GravityLowering.Lower fills from the
zone each frame; GravityLowering.CreateField makes the one quad. GravityFieldParityVerify renders it and compares every
texel with -Zone.GetHeight (max error 0.0059 u), the gradient with GetForce (0.03 degrees) and the wiring.
Deleted: the Gravity Well children of Planet, Gas Giant, Sun and PlanetOutpost prefabs, Wormhole 1's three gravity
children, their overrides in Main Menu and TestScene, five wormhole/wave materials and two brush shaders,
Planet.GravityWellDepth/Radius, BodyData keys 6-7, PlanetSettings.GravityDepth/GravityRadius (and the Settings.asset
keys). Surface Displacement culls layer 9 only. Headless build and tests not yet run at this commit.
