Attention: d3dx9_24.dll, containing D3DX9 library in DLL is included here only for testing on Delphi / FreePascal developer systems. Currently DirectX SDK EULA prohibits redistribution of d3dx9_24.dll with your applications. For developers distributing their apps via internet and not willing to force their users to download whole DirectX SDK it's a good idea to use previous relases of helper DirectX DLL's.
