reduz 2580ca01e6 Ability to keep collisionshapes and collisionpolygons when running the game.
Works for 2D and 3D
These are still just helpers in case you want to animate them or access them
directly.
Modifying the real shapes is still done via CollisionObject and CollisionObject2D APIs
But an API was added so you can query which shapes from CollisionObject correspond to which CollisionShape.

Have Fun!

possible algorithms:
Algorithm 1: (current)
definition of invalidation: global is invalid
1) If a node sets a LOCAL, it produces an invalidation of everything above
a) If above is invalid, don't keep invalidating upwards
2) If a node sets a GLOBAL, it is converted to LOCAL (and forces validation of everything pending below)
drawback: setting/reading globals is useful and used very very often, and using affine inverses is slow
---
Algorithm 2: (no longer current)
definition of invalidation: NONE dirty, LOCAL dirty, GLOBAL dirty
1) If a node sets a LOCAL, it must climb the tree and set it as GLOBAL dirty
a) marking GLOBALs as dirty up all the tree must be done always
2) If a node sets a GLOBAL, it marks local as dirty, and that's all?
//is clearing the dirty state correct in this case?
drawback: setting a local down the tree forces many tree walks often
--
future: no idea
