// DMTYPES.H
//
//   This "user" file defines the data types exposed by
//   the datamanager. It's necessary to have this global header
//   file so that enum DatamanTypes is actually unique. Maybe
//   a more clever way to do this would be to use Jon Blow's
//   profiling technique: declare a global variable for each
//   unique type, use the address of that global variables as
//   the symbolic name, and rely on the linker to generate the
//   unique names.

// this is an optional data structure used to alter models while
// they're being loaded. it could probably be done later in the
// pipeline, but this allows the whole thing to be subsumed into
// the data manager pipeline, so you can just use the model somewhere
// and it's automatically altered appropriately. Otherwise we'd have
// to have somewhere that explicitly loads the models and "preps" them.
