     uses the buffer passed in, with no copy
 
+While picking DOES use the aabb, getting things to actually HAVE an aabb is hard.
+    coz the _data_set() variation doesn't work, though that's the one we want.
+        Ah, it only works if you pass in EVAS_CANVAS3D_VERTEX_ATTRIB_POSITION, instead of _NORMAL, _TANGENT, _COLOR, or _TEXCOORD
+            Except it still doesn't!
+
+    So stick with the copy variation for now.
