* ObData Geometry Evaluation
* ==========================
*
* The evaluation of geometry on objects is as follows:
* - The actual evaluated of the derived geometry (e.g. DerivedMesh, DispList, etc.)
* occurs in the Geometry component of the object which references this. This includes
* modifiers, and the temporary "ubereval" for geometry.
* - Therefore, each user of a piece of shared geometry data ends up evaluating its own
* version of the stuff, complete with whatever modifiers it may use.
*
* - The datablocks for the geometry data - "obdata" (e.g. ID_ME, ID_CU, ID_LT, etc.) are used for
* 1) calculating the bounding boxes of the geometry data,
* 2) aggregating inward links from other objects (e.g. for text on curve, etc.)
* and also for the links coming from the shapekey datablocks
* - Animation/Drivers affecting the parameters of the geometry are made to trigger
* updates on the obdata geometry component, which then trigger downstream
* re-evaluation of the individual instances of this geometry.
