/* Black Box program for D3DParseUnknownCommand in ddraw.dll
 *
 * This program scaning all return valu that D3DParseUnknownCommand have in ddraw.dll
 * This command is not 100% document in MSDN so I using ddk kit doc and WinCE document
 * and ms ddk / ms sdk to figout the basic. and MSDN was unclare what this command support for
 * D3DHAL_DP2COMMAND dp2command->bCommand so I wrote this small scanner
 *
 * it will show D3DParseUnknownCommand  dp2command->bCommand support follow command
 *  command                 hex      dec
 *  D3DDP2OP_VIEWPORTINFO (aka 0x1c) 28
 *  D3DDP2OP_WINFO        (aka 0x1d) 29
 *  Unknown               (aka 0x0d) 13
 *
 *  no doc in msdn about command 13 (dec) I will exaime it later
