  15. *-- History ------------------------------------------------
  16. *
  17. * 2003.05.13:
  18. * Mongoose - New API, maintance cost was becoming so high
  19. * it was needed to sort out methods in groups
  20. * like my newer source code -- of course some
  21. * methods were altered or removed ( clean up )
  22. *
  23. * 2001.06.19:
  24. * Mongoose - New texture API for the new TR4/TR5 bump map
  25. * support, also purged textile exposure
  26. *
  27. * 2001.05.21:
  28. * Mongoose - Added to project OpenRaider, more documentation
  29. * than Freyja version I wrote ( 3d modeler )
  30. *
  31. *
  32. * 2000-05-13:
  33. * Mongoose - Added gcc and VC++ pragmas for packing
  34. *
  35. * id style typedefs for structs
  36. *
  37. * Heavy clean up and ported to C++
  38. *
  39. * I saved yuri's notes as best I could and
  40. * reformatted and corected as needed
  41. *
  42. * Mongoose - Created, based on:
  43. * tr_view's tr2io.c by Yuri Zhivago, PhD,
  44. * TR Rosetta Stone ( TombRaider pak format specs )
