   SetFVF
  Hey all,Quick question regarding the SetFVF() function and the D3DFVF flags. I'm currently trying to integrate a shader I wrote in that has the following vertex input structure:struct VS_IN {float4 Position : POSITION;   // in object spacefloat2 TexCoord : TEXCOORD0;float3 Tangent  : TEXCOORD1;float3 Binormal : TEXCOORD2;float3 Normal   : NORMAL;};I'm not quite sure what flags to set in SetFVF() to indicate that there is a tangent and binormal to the vertex included in this structure. So far, I've got ( D3DFVF_XYZW | D3DFVF_TEX1 | D3DFVF_NORMAL ).Thanks in advance.   
  D3DFVF_XYZ|D3DFVF_NORMAL|D3DFVF_TEX3|D3DFVF_TEXCOORDSIZE3(1)|D3DFVF_TEXCOORDSIZE3(2)ie: Position, normal, 3 texture coords, where texcoords 1 and 2 are float3.   ;  Thanks a bunch!
