// The naming convention for structures in Direct3D8 is a little
// inconsistent.  While all are in upper case, some separate wrods
// with _'s and some don't.  If you often have compiler errors that
// are spelling errors due to the inconsistent naming convention,
// you can define one of the following symbols to create typedefs
// consistent with either naming convention found in the header
// files
//
// RTM_NO_UNDERSCORE_NAMES  - use D3DSTRUCTURENAME convention
// RTM_ALL_UNDERSCORE_NAMES - use D3DSTRUCTURE_NAME convention
