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Algorithm 2: (no longer current)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
