Juan Linietsky e086bccd63 Import 3D Scene Improvements 
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

-If re-importing from the "dependency changed" dialog, edited scene will keep the local changes.
-Imported scene will keep track of changes in the source asset
-Geometry changes in source geometry or nodes with a different transform will be updated.
-Materials will be kept if changed locally.
-New nodes added will be kept
-If nodes were reparented or renamed, they will still keep track
-Deleted notes will be restored, use the -noimp option to avoid this.
-In general, you can trust that if you do local modifications to the imported scene, they will not be erased after re-import.
-Erasing your changes is done by re-importing from the "Re-Import" menu, re-opening the "Import 3D Scene" dialog. This wil re-import fresh.

Overall, This should allow you to work on a scene and see changes made to 3D assets in real-time.

So Please test!!

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Algorithm 2: (no longer current)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
