You can't set this value very well, since it's automatically computed
from the mass and the collision shapes. But since the values are higher
than many people might suspect, so being able to read it helps estimate
the amount of torque you might need to apply.
All classes were reviewed apart from VisualServer for which no argument name is documented at all.
While doing this review, I found quite a few bugs that were fixed either in earlier commits or this one (mostly documentation bugs though, i.e. some arguments were listed at the wrong place).
-KinematicBody2D::move now properly recognizes collision exceptions and masks, fixes#1649
-Removed object type masking for KinematicBody2D
-Added a test_motion() function to RigidBody2D, allowing simlar behavior to KinematicBody2D::move there.
-input now correctly works when using viewport scaling
-added function to get areas/bodies in given point
-added function to get space state directly from world
-=-=-=-=-=-=-=-=-=-=-=-=-=-=
-Removed "density" property
-Added instead more flexible "angular damp" and "linear damp"
-Added ability to override angular and linear damp in rigidbody
-Added gravity scale option rigidbody
Test well and iron out bugs, when it works the same will be moved to 3D

-New Vehicle (Based on Bullet's RaycastVehicle) - Vehiclebody/VehicleWheel. Demo will come soon, old vehicle (CarBody) will go away soon too.
-A lot of fixes to the 3D physics engine
-Added KinematicBody with demo
-Fixed the space query API for 2D (demo will come soon). 3D is WIP.
-Fixed long-standing bug with body_enter/body_exit for Area and Area2D
-Performance variables now includes physics (active bodies, collision pairs and islands)
-Ability to see what's inside of instanced scenes!
-Fixed Blend Shapes (no bs+skeleton yet)
-Added an Android JavaClassWrapper singleton for using Android native classes directly from GDScript. This is very Alpha!
-IMA-ADPCM support for samples, this means that sound effects can be compressed and use 4 timess less RAM.
-New 3D import workflow based on Wavefront OBJ. Import single objects as mesh resources instead of full scenes. Many people prefers to work this way. Just like the rest of the imported resources, these are updated in realtime if modified externally.
-Mesh resources now support naming surfaces. This helps reimporting to identify which user-created materials must be kept.
-Several fixes and improvements to SurfaceTool.
-Anti Aliasing added to WorldEnvironment effects (using FXAA)
-2D Physics bodies (RigidBody, KinematicBody, etc), Raycasts, Tilemap, etc support collision layers. This makes easy to group which objects collide against which.
-2D Trigger shapes can now also trigger collision reporting in other 2D bodies (it used to be in Area2D before)
-Viewport render target textures can now be filtered.
-Few fixes in GDscript make it easier to work with static functions and class members.
-Several and many bugfixes.
