- // ------- --------------
- // all message dispatcher functions take four parameters:
- // - reference to an object
- // - pointer to member function (signature varies according to the cracking
- // that the function performs)
- // - wParam
- // - lParam
- //

- //
- // LEGEND: in order to keep dispatcher names from getting too long, the
- // following abbreviations are used. The names are based on the data
- // sizes passed & returned, & which param they come from.
- //
- // - v (void return)
- // - i (int)
- // - U (uint)
- // - H (HANDLE) (requires special cracking, uint size)
- // - I32 (int32)
- // - POINT (TPoint&) (TPoint object constructed)
- // - POINTER (void*) (model ambient size)
- //
- // Possible future cracker encoding
- // Which param:
- // - 1 wParam
- // - 2 lParam
- // How cracked (default to no processing, size of param):
- // - U Ambient size uint (squashed lParam in 16bit land)
- // - L Low 16bit word
- // - H high 16bit word
- //
- // Custom message crackers are named based on the message they crack
