* Changes to DerivedMesh interface: DMGridData has been removed, getGridData() now returns an array of CCGElem pointers. Also added getGridKey() to initialize a CCGKey (implemented only by CCGDerivedMesh.) * PBVH: added BLI_pbvh_get_grid_key(). * A lot of code is affected, but mainly is just replacing DMGridData.co, DMGridData.no, and sizeof(DMGridData) with the CCG_*_elem functions, removing the reliance on grid elements of exactly six floats.
